@CalamityJane,
Would you be willing to pay for them? I'm actually serious, Amazon has a file hosting service where we can make code where they'd bill you for the file use. It's cheap at cents per GB/month.
We aren't ready to start hosting images again yet, the day may come but if members want to pay for their own bandwidth I'd be happy to make the features faster, I'm just not ready to commit to multimedia hosting as well.
I know other forums do it, but most other forums don't think out their long term viability too far. I just bought a forum that lost all it's uploads recently and know of no forum software that has an upload system that can actually scale with use.
So while it's possible, it's extra expensive and extra work for not much payoff. We'd do the work on the Amazon platform if enough members wanted it enough to pay Amazon for the hosting though, as it would scale nicely. Otherwise, the image hosting feature is a low priority for us, as it introduces business strategy complications that we'd rather put off till we have more overall scale and can absorb image hosting costs better.
