The Simple Gallery and Simple Gallery Random Modules are fantastic ways to give your site an extra edge.  You can organize thousands of photos in various albums and can then show them randomly on different pages.  Make sure that you play with this one a bit.  You can watch the video tutorials by clicking here.

In addition to the Simple Gallery Module that you see above, with the SnapShot Plus Package that you have signed up for, you have another photo gallery option with a ton of robust features.  It's called Ultra Media Gallery.  You'll find it in your list of modules and you can learn all about it by clicking here.
