Description:
------------
I get the following error when attempting to use this function on a CYMK jpg image.

Warning: imagecreatefromjpeg(): '/usr/local/www/vhosts/speaktomecatalog.com/htdocs/highRes/3STOOG.jpg' is not a valid JPEG file in /usr/local/www/vhosts/speaktomecatalog.com/htdocs/db/eproduct.html on line 153

But the same function works fine when the image is a RGB image.   

Is this a bug, or does the GD package just not support CYMK images ?

Thanks for your assistance.
Seth Russell

Not a bug (it is just not supported); so we make it a feature request.

I think GD added support for implicit CMYK to RGB conversion; does anyone know for sure? I'm having trouble finding information.

GD extension already provides basic CMYK support. See http://www.boutell.com/gd/manual2.0.26.html#whatsnew2.0.22

Indeed, CMYK is supported as of GD 2.0.22, which has been bundled
with PHP 4.3.6, see <http://php.net/ChangeLog-4.php#4.3.6>.
