This quick tutorial explains how to add images to both Atom and RSS feeds. Although both formats allow for image-inclusion, feed-reader support for image-display is currently quite limited. Hopefully, that will change in the near future..
Images for Atom Feeds
Images included within Atom feeds must have a ratio of either 1:1 or 2:1. There are no other restrictions as to file type or size. Use the
<icon> XML element for URL’s targeting 1:1 images. Otherwise, use the
<logo> XML element for URL’s targeting 2:1 images. Either element should be placed in the
<feed> <icon>http://domain.tld/path/icon.ico</icon> <logo>http://domain.tld/path/logo.gif</logo> </feed>
Images for RSS Feeds
RSS supports images with a maximum width of 144px and maximum height of 400px. If no dimensions are specified, 31px will be the default value for width and 88px the default value for height. Icons (
.ico) are currently not supported in RSS specifications. In RSS, it is possible to include additional image data via specified XML elements. Here is a complete example, commented with explanations for each image element:
<channel> <image> <url>http://domain.tld/path/site_logo.jpg</url> // *required! - the URL of the image <title>The alt attribute of the image</title> // *required! - the image alt attribute <link>http://domain.tld/my_blog/</link> // *required! - the URL of the website <width>111</width> // the image width <height>33</height> // the image height <description>An amazing website</description> // the link title attribute </image> </channel>
Customize as desired!
