I don't know how to tell John to send his I-phone photos to the site, so if someone else does, let me know.
1. Plug his iPhone into his computer, as he normally would to sync it.
2. The first thing that comes up (on mine, at least) is the camera wizard. Follow the wizard to transfer the photos from his iPhone to his computer.
3. From there, use the standard procedure to upload the photos from his hard drive to photobucket (or whatever photo hosting program he uses).
4. Post as usual.
Alternate method:
1. From the iPhone, email the picture(s) to yourself.
2. In your email program, open the pictures and save them to your hard drive. After that, follow steps 3 & 4, above.
Hope this helps!
