Getting error at the top when clicking pictures

[twiztidnati]

Hello,
I am getting the following error at the top of my browser:
Warning: Division by zero in /home/*****/public_html/screenshots/showphoto.php on line 1251.
This is only happening when I click to browse a picture, it does not appear at the top until I click into a a picture. Not sure why I am getting this, I installed 7.0 when it was in beta, I downloaded the new one, didn't see any difference so left it alone.

Another problem is that when you click into a picture, the top left home image turns into a red x. I am thinkin the problems are related. Any help is much appreciated.
Website it's on is .. MMORPG Screenshots - Gaming Screenshots - Wall Paper - MMOMadeEasy Gallery

Do you have any row or column settings set to 0?

I would say no, seeing as I don't even know where to find that. Additional information about where to find this would be helpful. Thanks, Richie

did you run your upgrade script?

did you upload all the new files?

I mean line 1251 of showphoto.php has nothing to do with any kind of division so something weird going on there

redownload the script upload all files except the config files run upgrade and select the 6.23-7 upgrade
