Hi Tommy, Wednesday, October 12, 2005, 10:48:55 AM, you wrote: > Is it possible to check if an url is a jpg image from php? #1 Quick and unreliable: Check if there is a .jpg or .jpeg as the final characters of the URL string. #2 Bit more complex, very expensive: fopen() the URL, download the content to a temporary location, inspect it with native php functions like getimagesize. If your PHP config allows, you can probably perform a getimagesize directly on the URL, but I've not tried this. #3 Trickier, less expensive than #2, but balls-on accurate: fopen() the URL (after suitable validation) and grab the header (the first few KB). JPEG files are easily identified, but come in a variety of flavours. http://www.codeproject.com/bitmap/iptc.asp Cheers, Rich -- Zend Certified Engineer http://www.launchcode.co.uk -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
