Depending on the version of PHP youre using you can use either
PEAR's Image_Remote class:
http://pear.php.net/package-info.php?pacid=42
Or PHP's native getImageSize()
http://fi.php.net/manual/en/function.getimagesize.php
To remotely get the dimensions of image file. IIRC the native
functions supports this since 4.0.5 and looking at the code
it does not download the whole image but parses the first few
bytes of the imagefile header (the same way as Image_Remote
does).
