SAVING PICTURES FROM WEBCAM

Question

Hi, there!!
I need to save frames from a Web Cam... How could I
do that???
Thank You very much!!

Answer 1

Here's how I did it:
The important thing to notice is that there's a few extra lines, this code actually grabs the frame, saves it to a file as a JPEG, then uploads that file to a webserver (but all of that happens in another class)
Hope this helps!!!
