[Web4lib] sourcing the website from which images have been downloaded

[jfitzgibbon at galwaylibrary.ie]

Hi,

We have three images which we have downloaded from one website and saved 
onto the hard disk of a PC, but we can't remember the website from which 
we have downloaded the images. This is a real shot in the dark, but is it 
possible to determine if the images have an invisible watermark, and then, 
use this information as a basis for searching for the website from which 
they were downloaded.

Regards
John
