Align RSS Images is a simple plugin that scans your RSS feed and ensures that every image has the correct alignment and margin settings. This is useful if you want the images to appear correctly aligned not just on your site, but also in your RSS feed.
Technically speaking, the plugin finds HTML elements styled with any of the WordPress-generated classes and appends an appropriate style attribute to each element. This is done dynamically when the feed is generated, so your actual posts won’t be modified.
Note: RSS readers that don’t support inline CSS will usually ignore alignment settings.
