I just added NextGen gallery.

If you go to this article I just put up, you'll see most of the thumbnails do not appear.

Does anyone understand why and how I can fix this?

does the thumbnail image exist?

Ah! I think that solves the problem.

I uploaded them all at the same time but for some reason only some images received thumbnails.

Thank you!
