Use imagesx(), imagesy(), or getimagesize()

You mean the filesize or dimensions?

Dimensions

getimagesize() will get a bunch of info about an image. Easiest way to get width and height is to assign it to list($width, $height) language construct.

Filesize

filesize() will get the size of bytes in the file. Divide by 1024 to get kilobytes and so forth.
