Image upload get file dimensions

["Chris Payne" <chris@planetoxygene.com>]

Hi there everyone,

In short, I use the following to upload an image to the server:

$max_size = 400000;
if (is_uploaded_file($userfile)) {

all works great, but what I want to do is store the file details in my MySQL DB, how can I easily find out the image width and height etc .... from the uploaded image so that I can store this information in the DB?

Thanks for your help everyone :-)

Chris
