cool. it's good someone takes a lead here!

would you mind publishing your code somewhere?
(e.g. cloning on github[*], and pushing your code to your personal 
repository, so it's easy to integrate once it's done.

Gem should be pretty verbose on the cmdline about what it does when 
trying to load the plugin (supposed it can find it)

no, that's the idea of the plugins.
Gem will simply look for files named "gem_image*.so" and try to load all 
of those.
the cmdline should give you some hints though, what goes wrong, if there 
is a file named correctly, and it still doesn't show up.

you code will need to have a line like:
  REGISTER_IMAGELOADERFACTORY(cocoa", imageCOCOA);

that will actually add the plugin to the plugin-factory.
