I've just been looking and find that my server does not have ImageMagick...so that's a deal breaker, right?
You need "GD libraries or ImageMagick" If your host doesn't have either on installed (hard to believe that a contemporary host would NOT have one or the other of these tools installed) ask them about getting it installed for you..
