Access a skins .png file out of Textures.xbt via python

Hi,

maybe i’m just lost for thoughts today, but i want to access let’s say the “DefaultAddon.png” image file which is included in the active skins Textures.xbt file.

seemingly won’t work – as i slightly suspected beforehand.
translatePath() does not seem to do the trick either?

Hopefully i did not miss something obvious.

Thanks for any hints to make this work!
