note 54100 added to function.imagegif

Using <IMG SRC="image.php"> to dynamically generate images is a bit problematic regarding cache. Unless caching is activated, IE seems to get confused about the type of the image when attempting to save it. A .GIF created in the above way causes the browser to suggest saving the image with .BMP, not .GIF. A solution is to activate cache with session_cache_limiter('public'); in "image.php", after which IE will correctly save as .GIF. If you do not want the cache to block any changes in the dynamic image, make sure that the SRC keeps changing with every reload. Something like "image.php/" . mt_rand(1,100000) . ".gif" seems to work well. Might be trivial to some, but I spent a couple of hours figuring out why IE always wants to save my dynamic .GIF's as .BMP's. ---- Manual Page -- http://www.php.net/manual/en/function.imagegif.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54100 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54100&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54100&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54100&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54100&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54100&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54100&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54100&report=yes Search -- http://master.php.net/manage/user-notes.php
