I would get for exampel ..Imagemagick..installe it ...and see if it fixes your problems...

it looks like the XOOPS code for detecting GD2 is flawed.
I have GD Version bundled (2.0.28 compatible)
this means GD 2 is bundled, implicitly GD 1 being suported too. Again, my webserver is a bundle from apache2triad.

Can someone show me a screenshot of some of their Admin pages (Categories or Forums) because mine is showing no icons whatsoever, which is the same problem I have on the frontend.

This all leads me to believe that the detection of the GD is the troublemaker. Can any of the cbb developers chime in on this for me?

Just thought I would add this for posterity. This is a screenshot from myalbum admin index. it too is having trouble recognizing GD2...when the GD2 test is run, but as you can see, the GD pipe works fine.
