Hi Ian,
Sorry for the delay in replying.
The fact that it found 5 is proof that it does work. However, the
program does not have full access to the photos on sites (currently
flickr only) and so can only trawl them slowly. SCF was only scanning
flickr for about a week before I had to take it down (I was trawling
too quickly). It's pretty lucky that it found 5 of your photos in that
week.
I've fixed the code and SCF is now back scanning flickr so more photos
taken with your camera may still get found in the future.
I've got plenty more features coming soon such as the ability to enter
the date your camera was stolen.
Cheers,
Matt
