I have a big problem with the otherwise outstanding NextGen Gallery. I use the thickbox layout for my galleries. It's normally working fine - unless you've got some embedded flash on your site, let's say a embedded youtube clip. When I click on the thumbnail and the image pops up the youtube clip in the background will overlay the image. Here's a snapshow of what it looks like: http://img18.imageshack.us/img18/6251/nextgentrouble.jpg
I found an old thread where someone apparently had the same problem here: http://wordpress.org/support/topic/185679?replies=16#post-1032776
I couldn't figure out where and in what file to put the code that was suggested as a solution though. My sincere apologies if I'm breaking any rules in posting this topic, but I didn't know what to do. The old thread had "resolved" in the headline and it felt like I was unlikely to get further help there.
I guess what I'm asking is: is it solvable with any of the methods suggested in the other thread? And if so, where and in what file do you put the code? And if not - does anyone have any further idea of what to do?
Thanks in advance!
