However, KCQuestor is right. Any image you can see on your computer screen is already on your computer in your browser's cache. If you know where to look for an image then you know you've already got it. But, like any home security system, the greater level of inconvenience it is to steal a picture and claim it as your own image, the less likely someone will do just that.
Also, when it comes to processing an image in photoshop so that it looks completely like a new image... why even bother? Why not just take a new image?
Most pic thieves aren't going to spend their time working on an image to make sure it doesn't look enough like the image source... like the honey badger... pic-thieves don't give a damn... they'll just download it and use it as their own.
