Thank you. Instead of doing actions 1 through 7 can you do just this?

Task: Test

A1: Get Files/Folders Properties [
Path: Kustom/wallpapers/
Type: Files
Recurse: On ]

A2: Flash [
Text: %lfp_full_path(*)
Tasker Layout: On
Dismiss On Click: On ]

%lfp_full_path(*) should return a random file from all subfolders.

Hope this helps!

Thank you for your suggestion but one question woundnt that take a lot of time to process? I mean tasker would go through all folders and files first and then choose one file out of all. 

I used to do it like that but at some point tasker took more time to choose an image before a new had to be chosen. 

Thats why i first told tasker to look at all folders and choose one to look more deeply into. 

Ok, you can do it it in 2 steps. But you can still use %list(*) to select a random element in an easier way :)
