Wallpaper set variable help

[cheese monkey]

Hi guys, first post after much help from these forums but I've hit a hitch. What I would like to set up is a way for Tasker to automatically set a variable when I manually choose a wallpaper. So I set Picture.jpg as wallpaper and Tasker sets variable %WALLPAPER ~ Picture.jpg

I'm sure (hoping) there's an easy thing I've missed!
Thanks in advance

Would it be possible to use %FOTO in some way?

Right having some success but % FOTO is last photo taken by camera rather than last photo viewed
