Image Technical Specifications

It’s said that a picture paints a thousand words, and images are the prominent “face” of your world so it’s integral to get it right. Ensuring your artwork closely represent the joyful aspects of your world, and looks attractive to relevant players, can help to improve the number of players that visit your world.

To submit your images, open the Mobile World Submissions channel on the Meta Horizon Community Discord and use the template provided to submit your world images.

Note: All images must be in .jpg format.
