I was browsing through some gigs here on Fiverr and I’m actually a little bit shocked when it comes to the tons of infringements of copyrights and portrait-rights here on Fiverr. I wonder how Fiverr reacts when it comes to serious claims from original rights owners.
You see, even if you have taken the image of a celebrity yourself, you cannot sell a gig where a celebrity is holding a sign or logo(!) without having the celebrity signing a model release first. This is also true for every other person, but celebrities have the more expensive lawyers who can put you through the shredder. If you want to use an image commercially you need a signed model release. Always!
If you didn’t took the image then you are additionally infringing the copyright of the photographer who did.
This are just some simple examples. It’s also an infringement to jump in a Spiderman or any other trademarked superhero’s suit and sell the gig based on that.
For those who want to prevent serious problems due to not knowing what they are doing I really can recommend watching this video of the copyright guys: https://www.youtube.com/watch?v=cGRvXB0d3dw&index=1&list=WL
