What would happen if you renamed a .jpg to say .pdf and did the download =
using the script above and then renamed it back to .jpg, is the jpg =
still corrupt? I'm just trying to ascertain if it is something specific =
to it having a jpeg extension or the jpeg data that=E2=80=99s at fault.

Alternatively you could zip up the images and have them download as a =
zip instead; we do this for one of our photo sites.

Also test on a separate server in case it=E2=80=99s a problem specific =
to the server.
