Pretty sure this is the wrong forum. But, when you sync, just look in windows explorer. It's handled like a camera is attached and the pics are there.
If you have wifi you can just email them to yourself. That's what I usually do when I don't feel like connecting it to my computer.
Wait a minute............ With the new 3.0, are you able to copy the screenshot, and then just paste it in a reply box?
Nope. It just comes up with the name of the image (like "IMG_45"). It's logical that it doesn't let you do this though since you can't just copy and paste an image into a reply from your computer... I usually upload images to an image sharing site or just copy them from my iPod in Windows Explorer.
