What *I* have found easiest is to store the image size with the filename in the database. So id=3 will also look up width/height. You may be able to use getImageSize() to get the info you need. NOTE: The size of the image DOWNLOADED to the client remains the same. PERIOD. Your scaling by 100 and 100 only does: 1. Scales the image on the CLIENT, after downloading the whole thing. 2. Tells the HTML layout how big a "hole" to leave until the image shows up. It never, ever, improves actual bandwidth. #2 *DOES* make the site 'seem' faster to the user, since they can read the text while waiting for the image. If your image is much larger than 100 x 100, and you are going to scale it anyway, you should look into scaling it on the server long, long before that HTML request comes in. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
