Yes, the paintings are in theory well suited for lossy compression. The 
only problem was that they contain transparency, which JPEG doesn’t 
support. But WebP does, even *lossless* transparency (with lossy 
compression for the non-transparent areas).

I hope it does. I have tested WebP on a few images, and while very high 
compression levels (of course) did result in visible artefacts, these 
artefacts were much less *annoying* than the corresponding JPEG 
artefacts. So with WebP we can probably use both high resolution and 
higher compression.
