The above command causes it to hang. Tracing through the code using a debugger it does look a lot like an infinate loop, though it could just be a really long one. I believe the infinate loop starts at line 155 in gd_gif_in.c at for (;;) { - I think it may just not be reaching an exit condition. I may investigate more later. Very strangely, if I download the gif and run the same command without going to the site at runtime, there is no such problem. Irid. ------------------------------------------------------------------------ [2004-06-14 14:02:11] [EMAIL PROTECTED] It seems this is Windows specific issue caused most probably by php_gd2.dll. ------------------------------------------------------------------------ [2004-06-06 20:04:26] jim at bluedojo dot com Yes, the images are corrupt. I believe that is why the function imageCreateFromGif() is going into an infinite loop. I need to have the function just exit and not loop infinitely. When I run the php page from the command line it goes into an infinite loop. When I load the php page from an Apache web server, it causes Apache to stall infinitely. My processor maxes out and I have to go to the Windows Task Menu to cancel the process. I am running the following: Windows XP Apache/1.3.28 PHP/4.3.7 GD library is turned on in php.ini Any help would be greatful. Thanks. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
