Hi friends, I have been battling with a bad problem of non-resolving jpeg images in PHP in my module Brilliant Gallery. It only happens in some systems. I then found this problem is independent of Brilliant Gallery -- it happens even if you open a static jpeg and then output it to browser. After many evenings of investigating this I have found that it happens after running Drupal's initialization: |drupalize(); function drupalize() { while (!@stat('./includes/bootstrap.inc')) { chdir ('..'); } require_once './includes/bootstrap.inc'; drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL); }| I have noticed - though I am not sure it is related, that after said initialization the 'Expires' header is set to 1978 - is that normal? Could you please have a quick look at http://drupal.org/node/186863#comment-742674 ... I have described my test precisely, with header dumps before said initialization and after it, so you will see all the differences. Hope some of you have some experience with this or related problem and will be able to help me -- and many other users. (I'd be so happy to get this working before travelling to Drupalcon!) Thanks!!
