To solve this problem, I simply replaced the image src path/file in the 
form tag with an image path/file that actually exists on my server. After 
doing this, the application worked properly.

Skimming through the documentation for this example, I do not see any 
caution about this problem. Is this something that is obvious and I should 
have known? (I did know to adjust the shebang line path to my executable 
python binary, and I did know to change the pop host to an actual pop 
host.) Since no one mentioned this possibility, it makes me think this is 
the first time it has come up on the list. Apparently the 404 error for the 
non-existent image file doesn't bother IE at all, but for Mozilla, it 
causes the process to fail. Kind of important??
