Hi all. I recently moved my Gallery2 install to a new server and now most of the images and thumbnails don't appear. However, some of them do and all the links to images from outside pages still work. I'm very confused. Any ideas?

Thanks
Eamon

EDIT: Problem solved using the thumbnail resize trick.
