What I found works very well for this is the function: getimagesize(); $image_file = "something.jpg"; $size = getimagesize($image_file); //$size[0] = height and $size[1] = width (double check on php.net)
//Then just divide them... $width = $size[1]/2; $height=$size[0]/2; <DISPLAY IMAHE height=$height width=$width> This way it will keep the original deminsions of the photo, just cut it in half, or however much you want to cut it down. Of course this approach makes viewing eaiser, but does not really cut down on the download time of the JPG, so if that is your primary concern, then another approach may be in order?
