[PHP] Image Dimensions

[NeoDreamer]

How do you check the width and height of an uploaded image with $_FILE?

Also, is there a "file exists" function in PHP? After the user has already uploaded an image, I would like to check on a different page whether the image still resides in the designated folder.

list($headw, $headh) = getimagesize("folder1/folder2/image.gif");

also works on .swf and like all image formats.
