Yes. Paste all 4 images into a single one by tiling them using paint shop
pro, or even an image filter. Generate texture coords based on the
sections. Apply Actor->SetTexture()

Very tedious and hard to get right.

OR...

Alternatively. Box has 6 sides. 6 textures from 6 images (or 4 in your
case) and 6 actors ...
Side1Actor->SetTexture(image1)
Side2Actor->SetTexture(image2)
...

Also very tedious.

vtk support for multiple textures is not great :)
