For switching forth and back between photos (both still ones and animated panoramas),
you may use the right or left arrows shown below each photo.
The up arrow will bring you to the overview page, scrolled to the thumbnail view of the photo just displayed.
On systems with (multi-)touch screen (e.g., mobile phones), in addition you may
swipe up on the screen to reach the overview page,
swipe to the left to advance to the next photo, and
swipe to the right to go back to the previous photo.
Within a still photo or panorama animated using HTML5/WebGL, you may click
on its upper third of to move to the overview page,
on its lower right to advance to the next photo, and
on its lower left to go back to the previous photo.
Within a panorama animated using Flash or Java, you may click
near its upper edge to move to the overview page,
near its right or lower edge to advance to the next photo, and
near its left edge to go back to the previous photo.
Inside the panorama displayed with the viewer you can navigate interactively. Doing so pauses the automatic movement.
The main control device is the mouse. You can pan horizontally and tilt vertically inside the scene by moving
the mouse while pressing the left button. The mouse wheel, as well as the Shift and Ctrl keys, can be used to zoom in and out.
When the toolbar is shown in the viewer, there are buttons for zooming in and out, for entering/leaving full screen mode,
for navigation, for starting and stopping the auto movement, and for showing/hiding the hotspots, if applicable.
Hotspots are clickable areas, which can be used to switch to different images. In this gallery,
clicking near the left edge of the panorama takes you back to the previous image,
clicking near the upper edge of the panorama switches to the overview page, and
clicking near the lower or right edge of the panorama takes you to the next image.
When the mouse pointer is hovering over a hotspot, the destination of the hotspot is indicated right to the toolbar.
Choice of browsers
To avoid compatibility issues and other problems, it is beneficial to use a modern, secure, fast, and standards compliant browser,
like the latest versions of Mozilla Firefox or Google Chrome.
Window resizing and scripting problems
Upon resizing the window, the size of the photo and text is adapted as far as possible.
Panoramas and browser plugins
If the panorama animation does not work, the likely reason is that neither a Flash player nor a Java plugin is available on the browser.
If one of these is installed, you may try enabling it.
Otherwise, you may download and install the Adobe Flash Player
or the Sun/Oracle Java Plugin. Then reload the page containing the panorama.
The Flash player variant is more efficient and is therefore the preferred one.
Text language and CSS incompatibilities
Some of the pages on this website allow for semi-automatically switching the text language.
If this fails, for instance because the browser does not properly support CSS tags,
then the texts are shown simultaneously in all available languages.
In this case, upgrading your browser is strongly advisable.
