See inside to change image It takes a really long time to load, there are 5 stages of loading (in order: black, red, green, blue, drawing) To change image go to see inside, go to RGB, go to costumes, change R to the red channel of your image in grayscale, G to the green channel of your image in grayscale, and B to the blue channel of your image in grayscale
