Hi Goodweather,
That previous post is all a bit beyond me I am afraid! I only know about valueTree for saveState and loadState, but if you want true flexibility with background images on tabs, you could cheat by having a component in a layer sitting below the transparent tabs object that changes (repaints) on a tab click. You can do anything with images in uiComponent including tiling all pretty easily.
Here is an example panel using metatable to initialise an image for the uiComponent on boot (that could be a transparent png for example)

JG
