On your Flicker page, right click on the picture and then click on "copy image location". Then come here and click on the little yellow box in at the top of the composing new message box that looks like it has two mountains and the sun or moon above it. It will create a popup. Erase the "http\\:" from the popup box and then right click and paste the image location info and press the ok button. This should drop the coding for the image location into the message box so that when you press "post quick reply" the picture should appear in your post.
