I have a digital photo that I took and have been offered money from various people for it. I do not want to give it up until I can register/copywrite it. It is my work and if there is money to be made from it I would like to know how to go about this. Is there some government department or company that will help me with this and a website I can send the photo to that will help me to distribute the photo online where copies of the photo can be purchased and I will be able to receive some sort of royalties from this?
Any help would be greatly appreciated.
