Quote - This is something that just inflates the download size, it's very very easy to reduce image size yourself if it's something you need.

But the flip side is that if it's that easy to do, the reason vendors don't do it themselves would be (in theory) to save a few bytes in the download size ... Does that mean vendors are somehow penalized for larger package sizes that they need to avoid offering it?

I'm a lot more likely to patronize a vendor that offers me a product that requires the least amount of work to make it work, letting me get on with what I want to do - use it :P

Stonemason offered a multi-app version of Tin Pan Alley (Poser, Daz|Studio, Carrera, Vue) - I would be interested to know if that affected their sales.
