Images!
Who doesn't love a little funny image to lighten up the mood? Well, thankfully Voices of the Void provides MANY ways to add a funny image of your own!
I will start with picture frames, they are the most straight forward to setup and envision in your mind.
To add an image, open settings, find the option that says: Open "Assets" folder
Then navigate to:
/paintings
/[type of painting you want to replace] (h for horizontal, s for square, t for table and v for vertical)
and place your image there in png format! Refresh the assets using the corresponding setting and you're done!
Example of a shack image, placed inside that same shack:
Next up: Posters!
Want a fancy piece of print to cover your walls? Well look no further than posters!
Same process as painting frames, except no need to find the corret type, just drop the png in "posters"
but, there is a quick tip I can give you! When making an image for one, make sure to keep it square and leave some transparent space like so:
It's to ensure that the image doesnt stretch (because anything but a square gets streched) and looks at least a bit pixelated to fit the game's visuals!
Stickers
Want to put your image anywhere? 
Well, lucky for you, VotV has support of showing PNGs as stickers!
Same process, stickers folder, square images prefered.
And quick note: not only can you even stick them onto 3d printed models (to be covered), the sticker pack you buy to stick them in the first place is infinite!
