Describe your idea
I would love it if there was a "randomize background" for image stills, just like there is for animations. I would love to have a different variation of menu stills in certain guis, but the only way i can do that is by registering a 1fps animation with one frame, which isn't really the most efficient and friendly method since it increases load times dramatically per animation

Does it frustrate you to not already have this feature in the mod?
it does just a tad, due to the only way i can achieve such a effect is with animations :c it would mean a lot to me if i could do this resourcefully!

my minecraft version is 1.12.2

Also, if possible, randomized image elements in general, not just for backgrounds? like picking from a pool to be applied to the image element would be really cool

Randomized layouts were added to FancyMenu v2.1.0!
This allows you to randomize everything, including background images :)
Thank you for your request!
