Erm, that's a license you have given right there. There may not be a 
lawyer behind it, but it is still a license.

I realise that for coders thinking of all these pesky legal matters 
is a nuisance more than anything else, but there are coders on trial 
for not looking at the legal small print at this very moment. We may 
not like the laws, but they are the laws nonetheless.

Here's the ImageMagick license as the main ImageMagick FTP site lists 

COPYRIGHT Copyright (C) 2001 ImageMagick Studio, a non-profit 
organization dedicated to making software imaging solutions freely

I'll have to look it up again, but the way I understand it, the 
ImageMagick license is a free software license, compatible with the 
GPL. Also, since you are allowed to add extra licenses to the GPL 
(IIRC, again, I'd have to look it up and am too tired at the mo to 
wade through the legal mumbo-jumbo), it would perhaps be possible to 
bring ImageMagick code under the GPL 

And of course, if we thought we could use some ImageMagick code, we 
could always ask the authors to also bring the bits of code we need 
out under the GPL. One is allowed to publish his/her own works under 
several, differing licenses.

This is a license too, although I am not sure you are enough of a 
legal representative of ImageMagick to supply it.

Oh, and IANAL.
