Quick and Dirty is for all those time consuming and ever repeating tasks. It isn't a monster like Photoshop; it isn't even a giant like Pixelmator or Acorn. But as a David it is much faster, much more agile, and thus for many, many daily jobs, often even more versatile.
Open, enhance, crop, resize, and save all your images for the Web in less than five seconds. Quick and Dirty will save you hundreds of minutes, or even hours, a year.
