Hi, I was searching for your site in Google, when I Googled 'zenphoto' it came up with a link to your site plus a lot of rubbish about viagra etc - I would guess that your site has been hacked in some way. If you try it yourself you will see what I mean.

Is the problem ongoing? Has it already been resolved (just waiting on GOogle to update cache?)
