Please be your own image host, externals suck..
Sounds like you want a way to hack the forum. This is how the forum was hacked in late 2013 and would likely be very vulnerable to additional hacks.
Oh, and start a bitcointalk wallet so we can all just stay here.. built into the site obviously
Also a bad idea. People should 100% control their private keys. Plus it would cause the forum to be more aggressive in restoring accounts when they are hacked, but it is very difficult to know for sure if an account is in fact hacked or not.
