What have you tried so far?
When I choose Media my photos fill the whole screen and so I don't have the option of dragging them (from a panel on the right as shown in the tutorial). I've tried to change that page view but haven't been able to figure it out.
What do you mean by "choose Media"?
You sure you haven't switched to iPhoto instead?
It sounds like it.
Either that or you have clicked on the green button of the Media Browser to make it full screen, in which case click on the green button again to reduce it, or drag the window back down agin from the bottom right corner.
