IMG tags removed from RSS feed

Hello,
I have a site which is publishing images and they never show up in the RSS feed. Simply, it seems any IMG tag gets removed.

The IMGs tags have been created manually and they reside outside the wordpress system.

Here is my feed:
http://www.funny-pics.biz/feed/

and the site is
http://www.funny-pics.biz/

My Settings->Reading page says:
For each article in a feed, show : “Full text”

and I have even tried the WP RSS Images plugin with no result whatsoever.

There must be a filter which removes images, knowing where it is would be perfect, so I can tweak it.

I tried several google searches on this topic, found may requests but no reply to this issue, any hepl is very very appreciated.
