Step 1: I am designing a website that functions so that a visitor uploads or emails a graphic image(usually jpeg maybe raw) to the website address to be modified in some way by me offline.
Step 2: The modified image (with a watermark) is then made available via email for the user to examine.
Step 3: When the user likes the result, he or she buys it through PayPal and the unwatermarked file is emailed to them.
I can handle steps 1 and 2.
Step 3 is the problem. This must be a 24/7 function. Any ideas?
Thanks in advance.
