Post your pics up on photobucket or flickr(not sure if it works on the albums, I'll have a try in a sec). RIGHT click on the image, select "copy image URL", come back to to your thread,
post a reply.
The reply button on the left, or if you did a "quick reply", there is a button below the box that says "go advanced".
Then above the box there is a little square with a "mountain" and a "moon" in it(yellow colour), a little window will appear, delete all the writing in the box(the http/: bit), then right click INSIDE the bit where you need to write the URL. Select paste, then OK, then post your reply, and it should be there!
