About three weeks ago I've sent my first letter to an inmate in a Federal Detention Center.
Today I had the returned letter in the mail including a note saying "No photos from home. Photos are only allowed from a vendor."
Can somebody help me out and explain the last sentence? I've read on the prison website that photos are generally allowed. Could it be that I've sent a photo from my hometown? Or do I have to send the photos from a special vendor?
I'm from Germany and don't really have a clue what' the problem?!
Thanks in advance!
