imagecreatefromstring() usage

[sonnysavage]

My setup:
Apache 1.3.24 and 2.0.36
PHP 4.2.1
MySQL 3.23.47

Has anyone used imagecreatefromstring()? The PHP manual is pretty scarce on information:

http://www.php.net/manual/en/function.imagecreatefromstring.php

I am trying to load a JPEG image from a MySQL table. From my understaning, this function is supposed to take many image types. I keep getting this error:
Warning: imagecreatefromstring: Passed data is not in 'WBMP' format in c:\www\mcsda\includes\class.image.php on line 16
Warning: Couldn't create GD Image Stream out of Data in c:\www\mcsda\includes\class.image.php on line 16

Judging from the error, I'd posit that the function expects a graphic in Windows bitmap format, not JPEG

WBMP images are for web-enabled hand-held devices like PDA's and cell phones. They are currently only displayed in black and white (monocrome).

WBMP support was just added to imagecreatefromstring() in PHP version 4.2.1. You can find it in the changelog.

I've reported it as a possible bug on the PHP site, but I was wondering if anyone else had used the function and knew of any tricks, tweaks, etc.
