I have taken a few screenshots on my iTouch. However these images are not synched like my other photos. The only way I can send them out is via email. This seems rather stupid. Why aren't they synched? Did I miss any thing?
If you're using a PC, navigate to "My Computer" then under "Portable devices" you should see "Apple iPhone", open that then open Internal Storage>>>DCIM>>>>100APPLE and your photos should be there.
EDIT: just realized your question said "screenshots" which if you mean screenshots of what's on the iPhone screen that would be under "999APPLE" instead of "100APPLE" (100APPLE is the location of photos, 999APPLE is where screenshots are located.)
Also, you can transfer videos from iTunes, iPod, iPhone to computer on Mac:
