Hi Scotty:
I assume you are shooting jpeg format and using a PC to process. In your photo editing software just save at a lower resolution or picture size. If you can let us know what software you use someone can probably walk you through the specific steps. There are unpteen different ways of do this.
On a PC with Photoshop CS3 it is [File] [Save for Web & Web Devices], in Elements it is [File] [Save for Web], in PaintBrush I don't believe there are sizing options, but [File] [Save As] and hit the JPG option will give you a low resolution copy.
I don't use the Microsoft shipped photo products, or the ones supplied by camera manufacturers, but another option is to download Google's Picassa, hit the [Export] command and/or resize the photo or lower the quality.
Hope this helps,
Dan
