sorry, maybe we are 2 stupid, but we can´t find to change the right look:

- left hand we want to have the file stucture
- in the middle we want to have the thumbnail view of the left chosen
- and in the right column we want to see for example the pics (when a pic thumbnail in the middle is clicked) in 100% size.
