From the message above, it looks like your project is missing the commons-io jar. You mentioned downloading and adding commons imaging jar to your project library folder, so I would assume you are not using a build / dependency manager tool like Maven, Ivy or Gradle? If so, may I recommend using one of those as they will automatically pull in transitive dependencies. > > I am an experienced java programmer but I have no experience with the > commons.imaging library.
