image missing in rss feed

Hi
My posts contain big images, since 1 day they do not show up in the rss feeds, 2 days ago they did, what could be wrong ?
The feeds work fine, just the image is missing, here is the code:

<?xml version="1.0" encoding="UTF-8" ?>
- <!-- generator="wordpress/2.0.7"
-->
- <rss version="2.0" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:wfw="http://wellformedweb.org/CommentAPI/" xmlns:dc="http://purl.org/dc/elements/1.1/">

I checked, the image is in:
wp-content/uploads/jan/_chloe01_01.jpg

Any idea?
