The getimagesize() function is used to find the size of any given image file and return the dimensions along with the file type.

$image = imagecreatefromjpeg($source); $image = imagecreatefromgif($source); $image = imagecreatefrompng($source);

Quality ($quality): quality is optional, and ranges from 0 (worst quality, smaller file) to 100 (best quality, biggest file). The default range is 75.
