I have installed the nexgen-gallery and have successfully created 2 galleries. I uploaded a zip file of images for a third gallery. I can view the thumbnails and click for a larger image but when I try to view this gallery in PicLens, the photos do not load. I haven't done anything different other than the zip upload and the file permissions for the 3rd gallery is the same as the other 2. Can someone tell me why this is happening and what I can do to correct it?
