After a great help from @C0d3man i’m trying to experiment with the great software.
Some of the pictures and thumbnails are not showing.
In stead of the original pictures it shows the default picture “No interface available”.
When i click on a pedal i get the right information but not the matching picture.
I 've looked in the directory structure and saw that the missed pictures are not available but the most are in different directories installed. (Not by me).
So are f.i. the “Calf” pictures JPG-files i.s.o. PNG
The working Pictures are all PNG files.
What do i have to do to put all the pictures in the right way and the right directory.
