Update (1/3/06): Find the latest info on RightSideUp on my main blog from now on.
A .NET application that automatically rotates images in a folder using EXIF data stored in the image by some cameras. There's no longer a need to go through each image and manually rotate them yourself. If your digital camera has support for storing an image's orientation (such as the Canon Powershot S330 which has the "Intelligent Orientation Sensor") then you should be able to use RightSideUp to automatically rotate all your images to their correct orientation.
