Error executing ImageMagick

[AmyDiane]

I'm in trouble again. This started about an hour ago. When uploading a picture coppermine complains "Error executing ImageMagick - Return value: 1" Is this an issue with my server, or is there  something  in the  script that  needs  to be changed?

Thank You,
Amy

choose GD2 as image Library in the configuration

To be exact, it's this value: http://documentation.coppermine-gallery.net/en/configuration.htm#admin_picture_thumb_advanced_resize_method

Now I'm really lost!
Switched to GD2 in the configuration. Now I get this error message:
"Fatal error:  Allowed memory size of 18874368 bytes exhausted (tried to allocate 13056 bytes) in /hermes/web10/b2564/moo.amydianenet/coppermine/include/picmgmt.inc.php on line 437"
I've looked at picmgmt.inc.php and can't figure out what needs to be changed.

Aloha,
Amy
