note 13665 added to function.imagecreatefromjpeg.php

I just wanted to note here something i found else where that was very helpful to me when using jpeg images. when using imagecreatefromjpeg() it can be difficult to allocate new colors. The work around i found was posted under imagecolorallocate() and prescribes that you first use imagecreate(), allocate colors, and then copy the jpeg into this image. http://www.php.net/manual/en/function.imagecreatefromjpeg.php
