Can not get Image Lists / Snap to work properly

[Kritter5x]

Hi! Mala is a wonderful Front End, it's given me a great amount of freedom in setting things up just the way I like, but I have recently run into a problem trying to get Image Lists for Tree Categories to work properly.

Firstly, I HAVE read the Wiki, toiled for hours and checked numerous similar topics on this forum in search of the answer and nothing seems to have worked. I have my tree set up like this:

Main Menu
   |--Arcade
      |--All Games
      |--Shmup
      |--Fighting
   |--Nes
      |--All Games
      |--Fighting

So that's easy enough. Next I have my images set up as "main menu_arcade.jpg / main menu_nes.jpg". I've also tried PNG's.

The snaps directory is set as the main directory of Mala, though I have tried every other directory combination, such as choosing the directory my layout is in, setting a dedicated snaps folder etc. I can tick "image list" just fine when setting up the Layout, and if I choose a default image, ONLY that default image appears. In the case of my layout, it basically reads "Arcade / Arcade" instead of "Arcade / NES"

Amusingly, if I add in a "snaps/titles" object into my Layout, that WILL display the correct snaps, even when I change menu item, but that's not what I want, I want an image based game list.

I apologise if there's anything i've missed out. Any suggestions of what I could try? I have seen others with the exact same problem as this but they never really wrote the exact methods for fixing their issues.

Thanks in advance.
