gtklock background image help

[iiTzSeb]

Back at it again from https://github.com/jovanlanik/gtklock/issues/123

Both HyDE and gtklock have shuffled around configs and I can't seem to locate the old config that used to be located in ~/.config/gtklock

Where's the gtklock config located in the current iteration and is the code the same as before to set wallpapers to it?
