For the first time, I tried using the blueprint function of the mod. The problem is, instead of the picture, it only showed a picture of a big red question mark. So here's a few questions on the limitations of the mod:

1. What is the minimum/maximum picture resolution that works?
2. Which image formats work, and which ones doesn't?

This is the image I'm trying to use as a blueprint, and I'm using Android and game version 1.10.
