Is there a way to scan a barcode from a pic saved in your bb file?

i.e. using my bb browser, i went to a website... saw a barcode i wanted & saved it as a pic. Now, as a pic, how do i scan the barcode? And, was there a way to scan the barcode from the webpage on my bb browser?

Is there an app that allows you to do that without using your camera as the scanner?
