hit the reply button - at the top there's an "insert picture" button (it looks like a yellow envelope) where you put in the link for the picture. Since you said it's on your computer you need to join a site like: http://imageshack.us/ so that you can have the picture "hosted" so that you can get a regular link to insert into forums etc. Then you can use that account for whenever you want to post a picture from your computer. This can be used at any forum or site that allows you to post a picture (many users here use that site). It takes about 5 mins to sign up and upload that picture, and it's easy to do.
We use FRAPs to record in-game and the program WoW Model Viewer to get some of those special shots of characters and green screen them in. Now for some of the camera movements a private server is used where you can fly around. But most are done in WoW zooming to first person mode either with actual characters using emotes or to film backgrounds in which we Chroma Key characters and effects in. Here are a couple links to getting started:
So the question is whether or not to rob a friend of £250, since if/when Blizzard identifies the account as being sold (which arguably, is not necessarily going to happen), the account will be banned... I'd still not sell the account. It is a disservice to an afore-mentioned friend at the very least (for the reason I explained). It also is not mine to sell. Any more than the Golden Gate Bridge is mine to sell. Interesting opinion. By the way, the person would be well aware of the risks - lets say it was their idea in the first place, so it cannot be called "robbing".
No screenshot, but my favorite crit ever as a dagger rogue came in Arathi Basin on my old server. I was level 49, had a Widowmaker with a +4 damage enchant on it. I was guarding the mine, and a pally had just ran by and given me a blessing of might, and I still had a warrior's battle shout effect on me (even more AP). Then, this undead mage runs up and starts trying to capture the mine flag. I was stealthed, of course, and grabbed one of those +30% damage rage bonuses, got behind him, and crit ambushed him for 1528. One hit kill. It was amazing :)
