This information may be dated and irrelavant, but since I'm dated and irrelavant it seems to satisfy me. This is a link to the microsoft store to download some of their toys. On this page you'll find an image resizer download. After you download it you can highlight a photo or every photo you have, right click, go to resize photos, and resize to small, medium or large. It's the fastest and easiest way I've found to resize. Unfortunately, this is for Windows XP. Doesn't work for Vista and I don't know about Windows 7. I run both XP and Vista, but use the XP system to resize everything because it's so easy. I think I size to medium, which is perfect for posting on the forum.
