Of course Google Images would back it, that’s where millions of people find images anyways. It could be very, very bad for photographers though. Basically, it would allow the use of an image if its owner could not be found and asked for permission. If you want to publish/make use of an image that isn’t yours you should be required (no exceptions) to ask the owner of that image for permission to use it. It is way too easy to just give up and claim you tried to find the artist. The bill needs to state specifically what is considered “diligent research” in finding an owner.
An extreme example – your a photographer and you take a beautiful picture of the ocean tide, a porn filmmaker uses that image in his/her opening credits. If you didn’t want your image used that way then that sucks for you. All the porn filmmaker has to say is that they tried to or didn’t know how to find you to ask for permission. The most they would have to pay is what the price would have been originally, nothing more. And they still get to use your image.
If the amendment is passed with its current wording it would make it legal to use an image if you don’t know who the artist is or how to ask their permission to use the image. If you get caught, worst case, you pay what you would have had to pay anyways.
One problem with it is that it puts the burden of arguing points of law on the artist/photographer. Possibly in court if it ever got that far.
