I have been using the same script on a live server running CentOS/PHP-5.1.6 and a development server running Fedora 9/PHP-5.2.3 for 1+ year with no problem. Recently I upgraded the dev server to Fedora 13/PHP-5.3.6 and now the same script has stopped displaying images. I have recompiled PHP, reinstalled http, httpd-devel, gd, gd-devel, libjpeg, libjpeg-devel, libpng, libpng-devel, and other related packages numerous times. But I can not figure out the problem. I would install PHP-5.2.3 on Fedora 13 but Openssl error out during the make process. ****************************************************************************** Here is some information about the liver server that does not have a problem. phpinfo: https://secure20.nexcess.net/thewordsmith.info/php/ Script View: https://secure20.nexcess.net/thewordsmith.info/resize_event_pic.php?event_num=27&new_width=100&new_height=143 Actual Image: https://secure20.nexcess.net/thewordsmith.info/images/event_images/2010-11-20/The%20Lake%20Effect%20Festival/Lake%20Effect%20Hip%20Hop%20Flyer.jpg Product script View: https://secure20.nexcess.net/thewordsmith.info/calendar.php ****************************************************************************** Here is info about the development server with the "imagecreatefromstring" problem: phpinfo: http://thewordsmith.dyndns.info/php/ Script View: http://thewordsmith.dyndns.info/resize_event_pic.php?event_num=27&new_width=100&new_height=143 Actual image: http://thewordsmith.dyndns.info/images/event_images/2010-11-20/The%20Lake%20Effect%20Festival/Lake%20Effect%20Hip%20Hop%20Flyer.jpg Production Script View: http://thewordsmith.dyndns.info/calendar.php ****************************************************************************** The logs are putting out "chunk" and "Corrupt JPEG data: 18580 extraneous bytes before marker 0xe2" errors. You can view all 3 error logs at: http://thewordsmith.dyndns.info/error_logs/ The development server is only on from 10am-6pm EST time.
