Clicking on the link to a picture activates the virtual microscope interface. It may open into a new window or a new tab, depending on the setup of user's browser.
Virtual microscope enables manipulation with the image. The interface is the same for all the images, but actual options depend on the image type. For example users can switch image planes, but only in those images, which were taken in more than one focusing plane.
Users can modify the interface to some extent (e.g. the language).
There are three levels of access to the virtual microscope: for users, teachers and authors.
