Felix, no one is calling you retarded! Anyways as for your problem what version board are you running, I have installed it on my 6.3.1.1 board, id say it should be ok to work with 6.3.1.2 too.
What I can see on that screen dump you provided, see the text where it says 'Never will you have to hyper-extend your fingers to add smilies. Don't quote me on that.' Then there is a broken link.
No that list should be populated with images found in your /ubb/gremlins directory
I think there may be something wrong with the path to your gremlins directory ? That would be the only possible reason the images are not showing where thet should.
