You have some great work, but I agree with slight-art-obsession, you really need to credit and link back to all the external images you use in your photomanipulations. Otherwise, one day you might be surprised to see someone reporting you for copyright violation or worse, you may face legal action. You have the chance now to make it right by crediting all the sources in your existing photomanipulations, but it's your responsibility to do so. Please keep in mind this is just advice that I am offering and not an excuse to complain. Better late than never to respect & acknowledge copyrights instead waiting till it's too late.
You might not be a magician, but if one day someone decides to sue you for thousands of dollars for copyright infringement, you cannot say you were not warned. This is a big deal, you have to credit your sources in your photomanipulations or you might have lawsuits filed against you, and that arabic website will not be able to help you. It's your responsibility and yours alone to make sure that you use external photos wisely and play by the rules.
