Problem with that, as I see it, is that uploaded pics directly to CB affects the bandwidth and cost directly.
Linking and the cost of that image is delegated to the hosting site.
I haven't spoke to Jefe about this, but I always assumed that is why linking pics directly is a CB "Premium" membership perk, because you are essentially covering your own data usage out of pocket.
That's the one perk that actually makes the most sense to me from a cost standpoint.
Maybe Jefe could fill in any details if I'm inaccurate.
