After a hot tip from one of its developers, I discovered Preloadr. Preloadr fully utilizes the Flickr API to bring you unparalleled photo manipulation capabilities. The coolest part is that you don't even have to make an account, just login to flickr and it does the rest. It automatically loads up the photos in your photoset and give you the ability to do everything from crop them to adjusting graduation, adding layers and text! When you're done editing an image, Preloadr uploads the photo to Flickr in place of the original. This tool is great for fixing up the crappy cameraphone pics we all take.
