This is no great feat of coding, but I did managed to get this little app to run forever, checking my upload folder, moving the files out of the 'uploads' folder and copying them to the 'processed' folder, and skipping over non-images, and having some minimal error handling for when corrupted images are uploaded. I also had to deal with some problems because I have OpenJDK installed on my Mac, and apparently for image processing I would do better using the Sun JDK. I was also told to use https://github.com/mikera/imagez, so I hope to come back and switch over to that soon.
