Best would be to achieve this in RSS 0.9 and 2.0
Well, in 2.0, add something like this to your wp-rss2.php file:
<image>
<title>YOUR BLOG NAME</title>
<link>YOUR BLOG LINK</link>
<url>YOUR IMAGE URL</url>
</image>
Title should allow text when your image is moused over and is also supposed to act like alt text in the event that the image file is not available, I believe. Providing a link as shown should also make your image clickable in aggregators. It’s probably something very similar in RSS 0.9. If you have a Feedburner account, you can easily activate this service with them and not have to pick through your code…
Would this also allow me to add geo ip information to an rss feed? Here is what goes into a page header:
<meta name=”ICBM” content=”32.219, -100.638″ />
