Which pictures can I use without permission?

Photos you have personally taken or those under public domain are the only ones you can use without securing permission. If a photo is found in a book, newspaper, magazine, or in any other publication, you must obtain permission first before you are able to use the image. Those than can be found on the Internet are also copyright protected. Furthermore, photographers retain the rights to their photographs, even if it is of you or a family member. Even if you purchased a print/copy of the photo, you still need to obtain permission from the photographer. When in doubt, get permission or talk to a legal consultant.
