I am using graphics in my PDF document. First I used something like this:
    \midaligned{\externalfigure[graphics/priceList][width=1\textwidth]}

Initially this worked good enough. But now I have both little pictures and pictures that are large in the y-direction. At this moment I change the width parameter manually. But I would like something like the following:
Is this something that is possible?

Also: is it a good idea to use \useexternalfigure, or is this only necessary when a picture is used more as once.
