PHP 4.03 + sessions = enable-trans-sid rewrite img src too

Hello I've compiled my php with the option --enable-trans-sid. Now, php add the SID to all the links and it's very usefull. But he rewrite the <img src=""> tag too. I thought i can fix it in the php.ini, but the url_rewriter.tags is like this : url_rewriter.tags ="a=href,area=href,frame=src,input=src,form=fakeentry" So, do you have any idea how to make php stop rewriting img tags ? Thanks. :+)
