I'm not sure how stripping 1 pixel strips a URL typed across the image, 'splain it to me.
Must be confusing URLs on the image with meta data URLs in the image, totally different.
As you mentioned watermarks before URLs and meta data in your list of tactics
watermarks, URLs, meta data,
I naturally took the URLs and meta data you were referring to as being "in the file" not "on the file"..anything "in the file" is stripped by a one pixel crop"..
On the file is "watermarking" whether the watermark is a URL or a phrase or a logo or a copyright symbol or any combination of them ..your website URL is the best one to put ( may get you traffic )..and the copyright symbol with the date ( gives notice to the cataclysmically dumb or thieving scum, that it s not public domain )..I have a script that prevents screen caps and all other ways of getting an image short of photographing the screen ..runs via jscript ( and jscript must be enabled to serve the images that it protects;)..plus the script itself is hidden and encrypted..heavily..run it with anti-hotlinking and my images are protected against everything bar taking a photo of the screen..
But I quit using it, many years back.. ( it has to take so much control of the browsers to nullify all possible copying actions that I actually was to all intents and purposes writing malware ( as it was indeed identified by a few AVs;)..plus it required the browsing machine to be rebooted before they got their cut and paste or right click back again after arriving on my page(s) ..not a good experience for the non larcenous visitors ;)
In the light of spark ( and doubtless the clones of it to come )..I may revisit it and tune it so as to not have the "reboot.. before you get most contextual menu commands and screen shot / print screen capability back" effect when it runs..
