JBred- You either need to resize the pics or convert them to .jpg. Most digital cameras use the .jpg format these days but the default picture size is typically huge. That's great if you want to make a poster to hang on the wall but forum uploads should optimally be less than 150kb in size.
If you're running Windows XP, the absolute best and easiest picture resizer is the Windows Powertoys resizer. http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
Scroll down to the Image Resizer and download. This should be a required add-on for every computer running XP. I'm pissed that they don't have one for Vista yet, it's the one feature I miss most.
