The RSS Image Feed doesn’t create a feed of images, but ataches the first image of the post to your feeds. Normally only the content has images showing. With our plugin there will be a clickable image even in the excerpt and in the content there will be only one image instead of all the images of the post. Since version 2.2 it works as a multisite plugin as well.
The plugin was tested up to WP 4.5 It should work with versions down to 2.7 but was never tested on those.

RSS Image Feed

The RSS Image Feed adds the first image of a post to your feeds, even in firefox and even if you only display the excerpt.

When WordPress makes an excerpt from your post content, it crops the content and adds an ellipsis […] to the end. This plugin changes the ellipsis to a Read More link to the full post content.
You can change the Read More link text to anything you wish from the Read More Excerpt submenu on the WordPress Settings menu.
Also from the Read More Excerpt submenu, you can specify the excerpt word length (WordPress defaults to 55 words).
Additionally, you can force the Read More link to show even when an excerpt is entered or when a read more tag is added to the content. This is turned on from the Read More Excerpt submenu with the Show More Frequently checkbox.
The Read More link uses the class read-more-link, so you can stylize the link any way you wish.
