That's up to admin and he makes that decision based on concerns about bandwidth usage and such. I asked him to turn on the [img] feature in one forum once and he gladly did it for me. I believe it was the evolution forum if memory serves. I personally would love it if it was turned on in every forum, but I think the bandwidth issue is a real hindrance to that.

PM admin with a link to this thread and ask him to respond to your question here.
