Somebody mentioned this in the Gizmo forum and it seems like such a fantastic idea I thought I'd bring it up here.
Basically, a program (ideally in Windows context menu) which operates like Tineye or Google Image Search but on local hard drives not the internet. You right click your pic, select the search and a target directory, and the prog finds images which are the same or similar.
I have a feeling it's probably way beyond the remit of coding snacks, but I thought I'd mention it anyway...
** My apologies by the way - I posted this first in the wrong place after reading the guidelines and forgetting to come to the right thread. If a mod could be so kind as to delete that one for me.
