Your PHP script doesn't even get started until *after* all file uploads have been completed, so that line of thought is a complete non-starter. The only place you're going to have a chance of checking the image size before it gets uploaded is in the browser using JavaScript (or an embedded applet in some other language such as Java). Cheers!

Re: [PHP] Quick imageSize question
Hey, Dont worry about talking crap, I took that risk when I started this thread :-) I was hopeing that maybe the image would have the info incoded in it which php could read before going through the uploador something like that. I too am not really sure if its possible, but am hopeing the "big boys" on the list who have worked on stuff like this for a long time will confirm it.

Re: [PHP] Quick imageSize question
Hello, that's usually not possible because your webserver can't access the image on your computer; a possible solution might be to determine the image size via javascript and submit it with the form, so you can accept or deny the image upload in your php script - problem: with javascript running on client side, this is not foolproof. Anyways i don't know exactly how to solve it with javascript even, so please correct me, if i'm talking crap here.
