RSS with Images is a WordPress plugin designed to enrich your site's RSS feed by adding featured images to posts. It offers customizable sizing options, making it easy to tailor the appearance of images in your feed. This plugin is particularly beneficial for users of email marketing services like Mailchimp, Infusionsoft, Hubspot, Constant Contact, Zoho, Feedburner, and Bloglovin', as it enhances the visual appeal of RSS-to-email campaigns.

Once activated, RSS with Images ensures that any new image added to a post will appear in the RSS feed, although it does not apply to existing images. Users can also set the XML encoding of their RSS feed, with UTF-8 as the default. This simple yet effective plugin helps users leverage their content better and improve engagement through visually appealing newsletters.
