This image gallery was the only one to work on my hosting service and i tried about 6 before this. It is so easy to set up and us. Its only a 3 step set up and takes about 5 minites to get up and running and a few secons to post an image.
The amount of features on this image gallery is amazing. It lets the user zoom in and out and print and save the pictures so easly using a mini toolbar.
All credit to the author and well worth a try if you cant get any other script working.
