Does anyone know if there's a script can be run to find out where ImageMagick is installed on the server? I know the thing is installed but i dont have root access. Thank you!

Try this PHP code:
<?php passthru("whereis imagemagick"); ?>

Or ask your host.

Haven't used it myself beyond this script but moveable type (the blog/CMS script) has a test file with it that checks for dependant modules - one of which is image::magick. Just grab it, read the install file and upload the test script.. easy :)
