Yep i really only want to target specific sites.

actually, hellswraith your apps figures seems pretty good compared to some of the 'professional' solutions out there. My maths is poor but i calculate that if your app can grab 15000 images an hour, 24 hours a day, 7 days a week, 4 weeks a month, that works out to about 10 million images which ain't bad at all compared to the blurb i got from a saleperson at digimarc (one of the biggest companies offering image watermarking/tracking).

"MarcSpider Reporting - this is our crawling service for the internet. We search for your watermarked photos across the internet and report back to you with the locations that we find them, a copy of the located image and the URL that we found it on. Digimarc continually spiders the web, looking at over 50 million images per month to find and report images that contain ImageBridge watermarks"
