I'd like to add a "simple" function to my current membership update form,
allowing users to upload a photo with their profile. My current process is
that I ask for a JPG image that's no larger than 250px on the longest side,
saved in the format LastnameFirstname1.jpg (some members are allowed 3,
hence the number at the end). They Email them to me, then I name them
correctly and manually upload to a directory. The profile page automatically
looks for LastnameFirstname1.jpg, etc., in the one directory.

Every class/script I've seen thus far looks way more complicated than I can
decipher, and I can't tell where/how to edit them to rename the file(s)
being uploaded. Has anyone seen a good file upload script, that's "SIMPLE"
to configure and use?

THANX in advance for any recommendations!
