Image Magick returns an error.

[hyperion]

Image Magick returns error numbers.  Activate debug mode to get the full error message.

Possible causes of IM error messages:

1. You have a space in the path to the IM Convert utility. You must not do this.   Windows users are advised to use a path without spaces, the short filename equivalent, or to set an IM environment variable and dispense with providing a path at all.

2. You have not set permissions for IM properly.  Remember that the server must be able to use IM.  Users of Windows IIS must give the I_ users (there are two) access the convert utility.
