By nature of the questions generated on this stack exchange, I'm guessing images will become fairly common. I see the StackExchange meta-thread on image hosting, but this feels a bit hacky to me: it still leaves us with the task of maintaining image links over time. Any other recommendations for how we might perform image hosting?
http://imgur.com is also good and recommendable.
I've been using http://imageshack.us/ in the last couple of weeks. It's pretty quick and usability is good.
I'd like it better if it could be integrated with a local screenshot manager so I can skip the step of saving it to disk first.
