You can always us yum from the command line in Fedora to install ImageMagik.
Example;
Code:
sudo yum -y update && sudo yum -y install imagemagik
should update your yum repo with the latest sources and then install ImageMagik.
If you get an error such as below you might already have it installed.
Code:
Cannot find a package matching imagemagick
No actions to take
A good Google search term for this would be;
install imagemagick fedora core 6
