This plugin works within the Genesis Framework, to display featured images in new and fun ways. It should work with either HTML5 or XHTML themes, but older themes may have a width set on elements which may not allow the full banner experience.
This plugin takes a different approach to how we use and display featured images for posts and pages. Instead of simply reusing an image which already exists in the post/page content, the plugin anticipates that you will want to use lovely large images for your featured images, but to do so intelligently. Depending on what you upload, the plugin will:
* display the image above your post/page content, centered and up to the width of the content, if your image is larger than your Medium Media Setting, and less than or equal to your Large Media Setting.
_Note: although this plugin requires the [Genesis Framework by StudioPress](https://studiopress.com/) or child themes, it is not an official plugin for this framework and is neither endorsed nor supported by StudioPress._
__Display Featured Image for Genesis__ allows you to select a default, or fallback, Featured Image, which will be used if a post/page does not have a Featured Image set, or if the post/page's Featured Image is too small (smaller than your medium image setting), and on archive pages. You may set the Default Featured Image under Appearance > Display Featured Image Settings.
You may set a Featured Image for each term within a taxonomy (categories, tags, and any taxonomy for custom post types). This image will be used on taxonomy archives, and as a fallback image for posts within that taxonomy if no featured image exists (or if the featured image is too small). If a post is assigned to multiple terms and has no featured image of its own, the most used term which has a featured image assigned will be the one used.
If your site uses Custom Post Types, you can set a Featured Image for each Post Type on the main Display Featured Image for Genesis settings page. If your single post within this type does not have a featured image, the Post Type Featured Image will be used as a fallback.
Now you can add the Featured Image from each post to your RSS feed. This is an optional setting and applied intelligently:
* if your feed is set to output the full text, the Featured Image will be added to the beginning of your post content as a full width image.
* if your feed is set to output only the summary of your content, the Featured image will be added to the beginning of your summary as a thumbnail, aligned to the left.
You can check/change your feed settings on your site's Settings > Reading page.
_If you are already inserting your Featured Image into your feed through another function or plugin, you'll want to remove that before activating this feature; otherwise you will have two copies of the image added to your feed! If you are using Send Images to RSS, don't worry about it. I've made sure these two plugins coexist happily._
__Display Featured Image for Genesis__ has some styling built in but I have intentionally tried to keep it minimal. All styling is for the banner image options, as the large options seem pretty straightforward. Stying for titles are largely inherited from your theme--for example, the title will use the same size and font for your page titles, whether you are using a Featured Image or not. Some styles you can incorporate into your own theme:
*`.featured-image-overlay` style appended to the post/page title if Move Excerpts option _is not_ selected (default).
*`.excerpt` (for single posts/pages) and `.archive-description` (for archives) are styled as a unit. These are the containers for the post/page/archive/taxonomy title and description if the Move Excerpts option _is_ selected.
*`.featured` is appended to the large image output directly above the post/page content.
_Set a Default Featured Image on the Appearance > Display Featured Image for Genesis settings page._
_Optionally, set featured images for custom content types, or change plugin behavior for custom content types._
Yes and no. Technically, it does, even older (XHTML) themes. However, depending on other factors such as the individual theme's styling and layout, the output may be unexpected, and require some tweaking. Not recommended for themes such as Sixteen Nine Pro, or The 411 Pro due to layout, and not for Ambiance Pro or Minimum Pro without changing some theme functionality.
### I'm not a huge fan of adding more JavaScript to my website.
As of version 3.1.0, you can choose to display even banner images completely with WordPress' native responsive images and CSS. No JavaScript required. Just visit the settings page (the Banner Output tab) and check the "Disable JavaScript" option. If you have previously used the banner (backstretch) featured image, you may notice that the output is slightly different, but it should be very close to the same, and easier to override with pure CSS if you need to.
### I switched to the scriptless banner image option and the output is more than a little different. What happened?
Generally, the banner images will display more or less the same whether you choose to use the JavaScript version or not. Where you may experience a significant difference is if you have the following setup:
* your theme CSS includes a max-height for the `.big-leader` element which is significantly different than the screen height (at least sometimes)
* your plugin settings leave the max-height for the banner image empty
The scriptless banner image position will ignore the parent container max-height. If you set the Maximum Height in the plugin, the new rule is added to the `.big-leader__image` instead of the `.big-leader` container. So if your theme is set up this way but you want to switch to the scriptless banner image, you can either enter the max-height number on the plugin settings options, or you can add the same max-height rule to your CSS, but on the `.big-leader__image` element in addition to the `.big-leader`. The plugin will add the rule to both elements if you use the setting.
The parameters/attributes for these mirror the widget options, so you can explore the code (or inspect the widget form) to find the shortcode attributes.
Alternatively, the much easier method entails visiting the settings page (under Appearance) and enabling the shortcode buttons for the post editor. With the shortcode buttons enabled, you can use the familiar widget form to build the shortcode and add it anywhere you like.
### What happened to my default/post type featured image?
If these images were saved to your database prior to version 2.2.0 of this plugin and you've never updated the plugin settings since then, these images may have effectively disappeared in version 3.0.0. To fix this, visit the plugin settings page, reselect your default/post type image(s), and save.
Prior to version 2.2.0 of the plugin, these images were saved to the database as URL strings, rather than as ID numbers, which was hugely inefficient. This was changed in version 2.2.0, with backwards compatible helper functions to ease the transition, but the helper functions are no longer used as of version 3.0.0.
Check the settings page before digging into filters. As of version 3.0.0, most questions/support requests have been implemented as options on the settings pages, including:
* setting a sitewide preferred image size
* setting a preferred image size per content/post type
* setting preferred fallback images for content types, search results, and 404 pages
* changing the default hooks/priorities the plugin uses for image output
Additionally, some of these can be overridden on any individual post, page, or content type, which can be set to use the default image size, not show a featured image at all, or force a large/banner image for that post only.
If you like to code, there are several filters built into Display Featured Image for Genesis, to give developers more control over the output. Several of them are very similar, and are applied in a specific order, so an earlier filter will take precedence over a later one.
*`display_featured_image_genesis_skipped_posttypes`: select post type(s) which will not have the featured image effect applied __(Note: this filter still totally works, but there is now a setting to handle this. It's on the Content Types tab.)__
*`display_featured_image_genesis_use_default`: force post type(s) to use your sitewide default image (set on the main plugin settings page) for the featured image effect, regardless of what is set as the individual post's featured image
*`displayfeaturedimagegenesis_use_post_type_image`: force post type(s) to use the image assigned as the custom post type featured image (if one is set), regardless of what is set as the individual post's featured image
*`display_featured_image_genesis_use_taxonomy`: force post type(s) to use a taxonomy term's image (if one is set) for the featured image effect, regardless of what is set as the individual post's featured image
__Note: as of version 2.5, you can set any post type to use a fallback image without using one of the above filters. It will use the images in this order as they exist: term, content type, default.__
*`display_featured_image_genesis_use_large_image`: force post type(s) to output the featured image as a large image above the post content, and to not use the banner effect at all
*`display_featured_image_genesis_omit_excerpt`: force post type(s) to not move the excerpt to overlay the featured image, even if the "Move Excerpts/Archive Descriptions" setting is selected
These filters all work the same way, so using any one in your theme will all follow the same pattern. For example, to prevent the featured image effect on the `listing` or `staff` post types, you would add the following to your theme's functions.php file:
Alternatively, you can also set a specific post type to use the taxonomy featured image, if one exists, even if the post type has its own Featured Image:
If a post has no featured image of its own, and is assigned to multiple taxonomy terms which do have images assigned, the plugin will opt to use the featured image from the most popular term (the one with the most posts already).
If you're needing to have a little more control than just specifying which post type to skip, and maybe want to use WordPress conditional statements, you'll want a different filter. This example disables the plugin on WooCommerce term archives:
### If a post does not have a featured image of its own, can the term, post type, or default featured image show in the archives?
Yes! This is a new setting, added in version 2.5. Please see the plugin settings page. If you were using the old method (`display_featured_image_genesis_add_archive_thumbnails`) to do this, the plugin will attempt to remove that from your output, but you may want to double check your archives.
This will follow the settings you choose in the Genesis Theme Settings.
If you do not want the height of the banner image to be quite the height of the user's browser window, which is the standard, you can reduce it by just a hair. Go to Appearance > Display Featured Image Settings and change the 'Height' number from the default of 0. The higher this number is, the shorter the window will be calculated to be. Feel free to experiment, as no images are harmed by changing this number.
_Note:___Display Featured Image for Genesis__ determines the size of your banner image based on the size of the user's browser window. Changing the "Height/Pixels to Remove" setting tells the plugin to subtract that number of pixels from the measured height of the user's window, regardless of the size of that window, which is partly why you cannot set this to more than 400.
If you need to control the size of the banner Featured Image output with more attention to the user's screen size, you will want to consider a CSS approach instead. You can use the plugin's Maximum Height setting, which will affect all screen sizes, or add something like this to your theme's stylesheet, or the additional CSS panel in the Customizer:
_Note:_ if your theme has CSS like this in it already, and you change the Maximum Height setting, it will (most likely) override your theme's styling, due to the order in which stylesheets load.
As of version 3.0.0, you can change the hook/location of the large featured image without code by going to Appearance > Display Featured Image for Genesis, and then the Advanced tab.
There is a filter for this, too. By default, the large (as opposed to banner) image is added before the Genesis loop, which places it above your post or page title. You can add this filter to your theme's functions.php file to move the image below your post/page title:
_Note:_ because the entry header applies to all posts on a page, on archive pages, this filter will be overridden with the default `genesis_before_loop`. To move the large image on an archive page, do not use a hook related to a single post.
* Now supports term metadata, added in WordPress 4.4. All new featured images for terms will be added to the termmeta table instead of wp_options. Old term images can be converted from the settings page.
