It’s inevitable that photos put online will be stolen. It’s a fact of life unfortunately. People think that just because something is on a website they can use it and claim the photo is there own.
Sometimes it just gets silly however.
With the help of Google Goggles on my Android phone I checked a few more photos. This photo of Venice (despite the author saying it’s in Pakistan) looks suspiciously like this one from the National Geographic. I’m sure they won’t be too happy to see that.
The Pictures2Win T&C of course include the condition that photos “must be the work of the individual submitting them” but there’s no link to report stolen images. I contacted Martin at that site. Hopefully he’ll take a look at that user’s account and take appropriate measures.
