I'm been using this wonderful plugin (nextGen Gallery) for a while now and I've never had any problems with it until yesterday when I installed it on a Web Site using a custom theme.
I go into the page and put my "Image List" and then go to the page and I see the thumbnails created and have the right size and everything. The problem arises when I click on a thumbnail to view the full size, original image.
The big image now shows behind the thumbnails and it messes up the background of the theme entirely, make it completely unusable.
If you have had this issue and found a solution, please post it and I will be forever grateful as I been going over this many times and can't get it to work correctly.
Thanks in advance
