Thanks for your replies.
I haven't run any of the ImageMagick commands from the command line no. Wasn't sure how to test that way without requesting the hositng company do the test for me. Perhaps I'm assuming too much, but it's part of their standard hosting package so I was trusting it to be in the right place, installed corerctly etc.
CodeIgniter wants to run 'convert' when ImageMagick is chosen, so I'm not sure the mogrify route is going to help me?
