Hi all, I've had lots of run-ins with this sort of problem - lol - and basically ...
1: PHP cannot determine anything about a file until it has it on the server 2: Javascript can create an object, and fill it, and then check the size BUT the file also needs to be on the server which just leaves Flash - which kind of does the same thing, it uses actionscript to 'replace' the contents of a movie clip with the image and then waits till its loaded and then asks how big it is (dimensions). Flash is the only known way to get any dimension related information from an image before it is uploaded. What most people do is let clients upload an image and then use php to delete it (or GD library to modify it) if it doesnt meet your criteria. Unfortunately this means that clients can still innocently upload a HUGE image straight off their camera etc and have to wait for the upload process to complete before you can let them know it was all for nothing :-( Since flash can talk to javascript, the best way is to write a generic flash file that javascript can call - get the dimensions and report back to js - and then relay any information necessary to the client or upload the file.
