It's true that *under the hood*, LC must handle each distinct 'flavor' of image differently. But why should *the user* be concerned about whether a given image is vector or raster or RLE or what?

Consider: Numbers can be signed, unsigned, integer, or real, and the engine's internal workings must handle each of those 'flavors' of number differently. But in spite of those internal differences, *the expression "VarX + VarY" ALWAYS just works, REGARDLESS of which flavors of number VarX and VarY happen to be*.

As far as *the user* is concerned, a number is a number is a number, and it *doesn't matter* whether a number happens to be real or integer or what. Why can't an image be an image be an image, *regardless* of whether an image happens to be JPG or bitmap or what?
