I got a request for hosting and domain registration for a 1-page site. No problem. The lady said she'd email me the web page for the site. No problem.
The first email of many arrived: "This pic forms the background of the whole web page. I have to send it in stages as I can't upload 16mb." The pic was 1600x1200, 270KiB, of a plate.
Then she started complaining that "I'm having trouble getting e-mail through to you. It's getting returned saying that you have too much mail in your account."
She forwarded one of the bounce messages. The error message read: "552 Message size exceeds fixed limit".
So I explained the "three second rule" and "ten second rule", that govern how long people are willing to wait to see anything on a web page. I explained the "hour and a half at modem speeds" rule that governs the viewing time of 16MiB web pages. I even explained the "640x480 screen users will only see about 1/10th of the 1600x1200 background image: or, a small section of the plate rim" rule.
It turns out she is USING 640x480. On a 21inch monitor.
My brain is bleeding.
