I would like to know how to replace the title and description of the feed (name of the blog) with a logo. Thanks
Depends on what specific software you;re using to create the feed in question. At the very least a link to the feed would be helpful. Gotta admit though last time I checked you weren't allowed to have anything but utf8 text within the title and descriptions tags within an rss feed. I'd have to look that up to verify it though.
