I realize NextGen Gallery isn't a WPMU plugin but it has really nice support for galleries. I've got 4 galleries I'm allowing the user to toggle back and forth between. The only problem is they do not want the image to popup, as NGG does by default.
I've got the image spitting out correctly but haven't figured out how to get rid of the popup yet. I know it is in the JS but there are a lot of files.
I'm not set up to debug very well in my current environment. IF anyone knows, it'd be huge.
