Dimensionizer is a simple to use and open source contextual menu plugin for the Finder that allows you to discover the dimensions of virtually any image in a single click.

How many times have you had to open the image you're working with just to find out its dimensions?  If you work with images regularly, chances are it's just too darn many!  Alas, rejoice! Your days of pain and sorrow are over...

Best of all, you don't even have to remember the dimensions to use them.  Just click on the menu item representing an image, and Dimensionizer will copy the dimensions to the clipboard.  Ready, set, go!  It's that easy.

Just install the Dimensionizer plugin and you're set.  Think of the time savings now possible!  You could shave literally, well, *seconds* off your workday!
