Chambered for? in mm or cm? Posting a photo is not hard.
There a pretty simple site on the web which I'm now using to post pictures and you don't even have to sign in or get an account. (account is free if you do want to sign up).
-- Pull up
www.postimage.org. -- Drag your photo to box entitled "choose images"...wait till a series of formulas appear.
-- Choose the one third from bottom entitled "hotlink for forums" and just click on it and select copy from your edit button on the top of your screen.
-- Then just post the copied link into your text.
