Description:
------------
When create a PHP file that outputs a JPEG image (with correct headers), sometimes the image gets cropped at some point and the rest of the image is corrupted and/or gray. When reloading the script several times I finally get the expected image. Saving the image to disk reveals the data is cut at some point, not fixed. The image is not very big (50-120 KB, JPG).

Problem occurs with both IE and Firefox. I have Apache 2.0. I've heard something about gzipped transfer between server and browser, but I don't really know the source of the bug.

Expected result:
----------------
The whole image at the output. The beginning of the image appears good but at some point, data is cut.

Actual result:
--------------
Saving image to disk, shows the beginning of the JPEG image OK, but cut at some point without any reason, and at variable offset.
