Are custom backgrounds/header/icon/splatters broken?

When I upload my own it just leaves a silhouette of the default gui.

-----
Also would be helpful if I can be told where could I find the menu buttons like Free play/multiplayer/Fight school and so on, can't find them in the textures folder.
-----
Was only able to make the silhouette appear white, which still doesn't look pretty.

Are you sure they are transparent?

Forgot to update, ended up figuring it out, a few minutes after posting.

Just need the source of the free play/multiplayer/etc textures.

Bump?

E: \Game files\Steam\steamapps\common\Toribash\data\textures

I already checked there, so i'm asking here cause I cannot find them,

If you can be more specific (file name) that'll be really great.

Those aren't textures.

My mistake, thought Lucy meant the default textures for GUI.

Surge and I were looking for them ingame, sadly never found it, do you know where I could edit the settings to get something other than white?

moved to technical support, seems more appropriate here.
