if you would like a more basic photo gallery try
micro photo gallery it is a program where you just put the file in the folder with all the images you want to have in the gallery and it automatically scans the folder and creates thumbnails. It is very clean nice and simple if your just looking for a really easy and simple script. I love it! If you have any questions or need help with your site Message me!
Also a very good question by blakcheez. What is your experience and comfort level?
