This extension converts px image dimensions into em dimensions.
If your layout is fully based on em dimensions you might want the images to use them as well.

Therefor, a hook in tslib_fe is used and the classes tslib_content and tx_cssstyledcontent_pi1 are 
extended with an ux class. So, if you use another extension which also extends those classes, please
check if there are conflicts before you install this extension in a production environment!!

As the width and height calculations with em are relative, you need to provide a base value for the
calculations. You can either set this globally, for each column or for each content element. If you
use a base value of 10px (which makes calculations easy) in your main content column, you can leave
everything like it is set by default. If you have another base value, just set it in TS globally or
for each column or insert it into the content element itself (page=>edit CE).
