You are not restricted to posting one pic a day if they're you're pictures and you claim copyright to them. You must say something like "all pictures copyright TeentyPence" with each picture you post, but the pictures MUST BE YOURS. I only post pictures of myself and therefore put my copyright in my signature, but I can then ONLY post my own pix. Some people like to write out the copyright each time they post one of their own so that they can omit the copyright line when posting someone else's pictures.
