Hi TIM-
I don't know for sure what the problem is, but I have AOL and sometimes pics are sent in a Zip format and as an attachment. They may not automatically open. Unless the receiver has an unzipping program, the pics will not open up. Also there are several settings within AOL re: mail and pics and attachments. Your receivers should take a look at what their mail controls are. They may have set the security setting too high to be able to look at attachments, and they might have parental controls active.
Sometimes the pictures are sent to the Download Manager and will only open up when specifically told to by the receiver.
When I receive pics, the timer bar will ask if I want to open them up right away, and it will do so. But if I opt not to look at them then I will have to find them on the computer to view later. They are normally sent to the Download Manager in that case. However, if the receiver doesn't pay attention to where the pics are sent, they may be sent to another location of the computer.
If the pics are in a format that AOL doesn't use, they may be stored on the computer. The receiver can then use a program like Infraview to convert them to an AOL compatible format.
Sorry to be so iffy and lengthy. But there are loads of variables.
Infraview is a wonderful little program to have. It helps to open up lots of various formats. Once you find the unopened file, you can send it right to Infraview.
Maybe someone else can clarify what I've said.
