I have had some blank pages as well in the past, but I found out that it has to do with the number and size of the photo's:
when you have many pictures (I saw 75 pictures in 1 of your albums), and also of a big size, then your server gets too busy with the pictures.
I solved this by putting max. 20 pics in 1 time in an album, AND be 100% sure to wait till you have the little blue pics on the right that say "Done" or "OK".
I'm not sure if this is a problem of the module, or of my (and your) server, or that it's logical that this happens with large (amount of) pictures, but I've learned to live with it.
It's a great module apart from that!
Well, I could use a cold beer right now!!
Greetz,
[Edit] What theme do you use btw, is it a public one or a self made? [/Edit]
