It will download only the first 24 bytes instead of the whole image, and thus being much faster than getimagesize() and it will save bandwidth at the same time:

There's a code snippet for getting JPEG image dimensions by getting only first few bytes of the file, but it doesn't work for PNG files, so I wrote one. I wrote a function to get the size of a JPEG by streaming bytes until the proper data is found to report the width and height: Since the width/height is in the first few bytes of the file, there is no need to download the entire file. This is extremely slow on large images that are accessed remotely.
