I want to add an author bio to the right hand side of my website to make it look legit. The website is amazon product review, but I want to do lots of commenting on people's blogs so I need a face to go with the website. However, I don't want to use a 'free' stock image because you can pretty easily use Google images or TinEye and realize that its not unique. Is there any way to buy a picture that will never have a match on the internet? I realize I could apply filters and stuff, but I don't want the photo to look edited.
