I tried NetPBM as well. Nomatter which I use I get:
Processing status...
No images uploaded!

And I can only get this response by going to add photo(s). By just choosing add photo it just stays at the copy screen.

When I go to check_netpbm.php I found these errors, but have no idea how to fix them:
