Here is 2 things you may want to do. When you re due the Image size also change the resolution. If you are just putting them on the net to share re due the Res to 72. and image size around 640 x 480 see if that helps you out
After you are done with image and have saved it as a jpeg or whatever, you can also easily shrink it with an image resizer Powertoy downloadable from Microsoft. Photoshop is still better, but if you don't know how to read the resolutions, you can use this nifty tool.
