Welcome to the eighth of 31 applications we will post (in addition to the contest participants' submissions). Make sure you add this blog to your RSS / Atom feed and check the gallery for summaries of all the apps as they are released. 

This application demonstrates linking two viewer controls together; one working as the main viewer while the other provides an overview of the entire image, outlining the currently viewable area of the main viewer.

This setup allows the end-user to quickly scroll to a specific area of the image by dragging the outline in the overview image. 

To use this application, select Open from the File menu and choose a file to view.  Once the image is loaded you will see a blue outline in the image overview.  Grab this outline and drag it to the area of interest and the main viewer will automatically scroll to this position.
