To add your own photos: change one of the costumes. To add a new picture: duplicate one of the sprites, make the message receiver block in it recieve an new message with the name of the next number, and change the backdrop's pick random block to include that value Note: the photos here are 1024x1024. A consistent photo resolution is helpful when mixing images. Also, when changing the number of photos to mix, you might also want to change the ghost effect values of all of them to a higher, if more, and lower, if less, number.
Some of the photos are AI generated while others are of my real dog. UPDATES TO COME!
