hmm... is it only me, or can anyone else NOT see the pictures in this thread?
*looks through page source, as usual*
well, i think the non-shaded icons look better, but it also depends on what kind of background the person is going to be using in-game. i usually go for a darker background, and so something being shaded would be harder to see, so i would go for the unshaded versions. for someone with a brighter scheme, they may want to go for a darker icon, because light on light, as with dark on dark, is harder to see, so i vote for having both in the installation, but the default being the unshaded icons (a separate folder outside of the textures folder, which can just be c/p'ed into the textures folder if they want those instead).
p.s. could you link to the image itself, and not the image gallery, so that i can see them? i would be very happy if you did
