I can confirm that the Smilies don't look good on a black color.
I guess, we'll have to look for a new set of smilies for XOOPS 2.6.0. Anybody has a recommendation for free transparent set of smilies? Or could make a set for us?
In the meantime, you can use this set:

Either rename the individual icons as needed, or you can use
Avaman to add the new icons, and delete the old ones.
