How to eagerly load images instead of lazy load?

[SamuNatsu]

I have some images to be shown, they will be acted like a frame-by-frame animation.

But when I try to show them, it sometimes shows a loading spinner before showing the image, which indicates the image was loaded lazily.

Can you load all the images into byte arrays prior to rendering using fs::read()? That way the images are all in memory prior to loading into egui cache and rendering.
