So Imagemagick or GD? I don’t know all depends on your needs. I’m really not that familiar with the difference between them to be honest. I know there are some benchmark tests and the such out there but I have not really invested time in reading up on it. As such both work just fine for my needs. So I usually install both, as some CMS require Imagemagick and others GD.
You can grab a Imagemagick [here]. As of writing I have only been able to successfully install version 6.8.0-8. The install procedure however is the same for all versions. I guess it will end up in “trial and error approach” regarding what version you get working.
tar zxvfp ImageMagick-6.8.0-8.tar.gz cd ImageMagick-6.8.0-8 ./configure make install clean
Finally test if things are working as intended.

If this completes without errors you are good to go.
And we are done here.
