Do you need a way to get image data out of a jpeg? It might seem like pulling teeth sometimes if you need any more than just the basic date/time of the photo or what camera was used.
But what if you would like to know the subject, city, state, or location of the photo? Or what if you would like to provide shutter speeds, aperature settings, etc...? Then you have to search high and low to figure out how you're going to get that information out of an image.
This project is simply about a class library that will allow you to get (for now) and set (in the future) information about a JPEG image without trying to figure out what all of the possible paths are to get that information using a BitmapMetaData reader.
