or maybe obscure...
I was reading a photography forum and a reference was made to how you can use google to search for a particular image. (if interested, see http://www.google.com/insidesearch/searchbyimage.html)
The discussion centered around copyright infringement...basically stealing people's photographs posted on line and either claiming them as your own, or using them without attribution (and compensation) or the worst I guess, selling them. Being the curious type, I searched a few of my photos and was shocked...SHOCKED I tell you, to find that some of my photos have been used without attribution:
Possibly my favorite photo of all time, blogged HERE
Shows up at a travel site page about Kakadu HERE
One of my very recent photos taken while on a return visit to Sarajevo, taken from Shelby's balcony. Shows up in a thread "The Skylines in Eastern Europe"
One of my Plitvice photos shows up in a thread all in Cyrillic that I can't read.
A Lake Bled photo is linked on another travel site
And my blog entry about Sutjeska Monument has photos showing up a number of times including twice on this site.
Last, one of my earliest blogged photos is apparently "for sale" or for upload to your facebook account...it's making me rich!
The coolest part though, is how many people apparently look like an elephant....or a tombstone (see the "Visually similar images" :)
It is also cool how google tries to figure out where and what of the photo is taken.
