Above this smiley
on the upper left, below the "B" BOLD
Icon, you'll see this icon
click it and you'll see this appear where your cursor had been resting last img][/img, between the two brackets you see here ][ past the address of the pic you want to display.
You can snag the address by right clicking on the pic body and select "Copy Image Address" then paste that address between the brackets.
Hit quote on my post and see how I posted this pic.
