I have been using the above code to produce an image gallery. I drop the images into a folder alond with the script and bang an image gallery.

I would like to modify the code so if the amount of images are more than a given number (maybe 16) the script probuces a PAGE 2 link and the remaining pictures are displayed on there if it reatches 16 again PAGE 3 is made.

Is this possible?
