FancyBox for WordPress

Having problems. I uninstalled this before. figuring it would go back to the way it was just installed again, and still having the same trouble before i updated the overlay pictures came in awsome now there all muffed up!

I’m using FancyBox for WordPress ver. 3.0.2

When, I click on my image lets say if someone left one in the comment section it will come up as an overlay

First link shows you its in overlay mode.

Now as you can tell the image isn’t in front of you. But if you scroll down the screen actually turns to a shade of grey and your overlay image is down at the bottom.. but you can’t scroll down to the very bottom, it won’t let you. If you keep holding the button pg down, you will see like a small tad of the picture..

I don’t know what’s going on please help..

Also.. same goes with when I use ‘Easy FancyBox’

and ‘FancyBox’ just seemed to hard for me to understand, I guess i gotta code a few pages for it to actually work ehh..
