Since I have a PC click on the window you have the webcam program open in
Do the Alt-PrtScrn
Paste into any program you can paste into like Word, Notepad, etc
Open the Snipping Tool under Accessories
Clip the portion of the window you want to save as a picture and file it as a jpg
Open the jpg with Microsoft Office Picture Manager(any picture editor with resize) and Resize the jpg to something with less than 640 pixels
Then import it into YachtForums!
If this does not work please advise what kind of computer you are trying this on, operating system, etc.
Good Luck YN!
