Thanks Gizmo.
I added the path which I located using "locate mogrify" and it comes back /usr/local/bin which is what I put in the path. I can see the ImageMagick in the drop down list now too.
But, for some reason when I attempt to make a new user and enter the reg screen the CAPTCHA generator fails to make an image. Any guesses as to why?
$ locate mogrify
/usr/local/bin/mogrify
/usr/local/include/wand/mogrify.h
/usr/local/man/man1/mogrify.1.gz
/usr/local/share/doc/ImageMagick/www/mogrify.html
convert -version
