Is PreloadAsync Not Keeping Images Loaded?

[MapleMarvel]

I am using the code from the documentation to preload images that will be used for an animation.

local ContentProvider = game:GetService("ContentProvider")

local frame1 = Instance.new("ImageLabel")
frame1.Image = "rbxassetid://111111111"
local frame2 = Instance.new("ImageLabel")
frame2.Image = "rbxassetid://222222222"

local assets = {
	frame1,
	frame2,
}

-- Preload the content
ContentProvider:PreloadAsync(assets)

Then I am playing the animation by updating the image id during Heartbeat:

-- Play frame 1
ImageLabel.Image = "rbxassetid://111111111"
-- At next heartbeat, play the next frame:
ImageLabel.Image = "rbxassetid://222222222"
-- Etc

The problem is that when I play the animation, the images that were preloaded seem to have been offloaded by the system already, and are no longer preloaded.

The only workaround that I could find is discussed in this thread:

Preloading images and keeping them loaded!

Preloading images and keeping them loaded! Are you tired of your game not having assets loaded when entering a new scene? Is PreloadAsync not keeping the textures loaded? I found myself in this situation so I’m making this tutorial to help others. Step One Make a list of all the Asset IDs you want to load. This will be used to create the ImageLabels that forceload the assets. local assets = { "rbxassetid://1", "rbxassetid://2", "rbxassetid://3", "rbxassetid://4", "rbxassetid://5", "rbx…

Am I doing something wrong to cause the images to be offloaded? Thanks for any suggestions.

Changing images in general can be buggy and has a lot of flashes, it would be better if you used something like a sprite sheet and changed the ImageRect stuff
