Weird problem with photos

Been loking thru forums for a week have not found a similar problem I am not sure if the problem is image handler, my template, or some setting in general so i am posting it in the general area. I am using zen 1.5.0 Have image handle 4 installed, google base feeder, and the desert noon template. When I load some pictures It crashes my site, this is what it does:

http://zc.desertmoonleather.com/index.php?main_page=index&cPath=3

I will leave it in this crashed state till I figure out the problem

I can take the picture out and leave the posting and it works fine, it started with some working and some not, now no picture will work.
I have very little tech skill so if you respond keep that in mind,

Thanks
Mike

Just unistalling the addon works fine without anyway
