Leif, I'd like to see that...
To post a pic, first you must ensure that it's only about 600 to 700 pixels wide.
Then you go to
www.imageshack.us and upload the pic. Once it's uploaded you go to the first line below the stuff on the centre of the screen that's showing, that line has a check box 'include details'... uncheck that... and at the end of the line it says 'hotlink for forums 1'.
You simply left click in that line, right click and click on 'copy', then without changing a thing, put your cursor in on a fresh line of your post and right click, then click 'paste'.
