Newbie question - Don't even know to phrase it

Hi there
I have a flash scene where I import a scanned jpeg of a dvd cover. When I attempt to resize it it resizes (how can I describe this) relative to the cente of the image rather than from a corner. This makes it difficult to fit it inside a frame because even when I align it to one side and then shrink it it shrinks from both sisdes simultaneously I then keep having to recentre in and then readjust. In my older version it seems to me that it just resized from the corner and wass simpler to do what I need to do
Any suggestions?
Thanks a lot
