Hello everyone.

I first mounted on igo 2.4 diMkaWA_P174_TomSoft_ a skin (a), that's fine but many times when I go into the gallery appears on the left kind of a beveled rectangle that indicates down the length of the tunnel along the path of the gallery as a thumbnail.
The problem is that many times the black background where the arrow appears with the path actually is purple so you can see almost anything within the rectangle.
On what parameters should I act or what icons I have to step in to give the background miniature always black?

greetings Felixx1
