You can have any numer of picture windows open at the same time. Each window is provided with a row of buttons:

1.   opens or closes the window with the list of signs
2.   opens the magnifying window
3.   closes the magnifying window
4.   closes the window with pictures
5.   focusing up
6.   focusing down
7.   enlarging the basic picture, which can be dragged

Opens or closes the window with the list of signs. The list of signs is opened in a separate window. The text is generated from the database of signs and sometimes additional notes are added. When moving the mouse over the text of a sign description the background of the text changes to bright green and the arrow (or other signs) appear in the picture. After moving the mouse off the arrows disappear. After clicking on the sign description the background turns dark green and the arrows are fixed until another click.

Opens the magnifying window. The small window with high resolution picture will open. The picture will scroll according to the user clicking in the picture with the basic picture, showing the detail. Note: Some pictures may not have the high resolution button available. That means such picture is available in low resolution only (fluorescence etc.)

Closes the magnifying window. Always use this button to close the high resolution window!

Focuses up in pictures available in several focusing planes.

Focuses down in pictures available in several focusing planes.

Closes the basic window (and associated windows with signs or high resolution as well). Always use this button to close the window!

Enlarges the basic picture by a factor of (approx) 2.5 (no image degradation will occur, but rather new details will appear). The image can be dragged by a mouse (click and hold the left button). The same button will decrease the size of the picture back. This button is available in those pictures, where there is large difference in size of the image in the basic and high resolution window. The arrows will deactivate the zoom and vice versa (the arrows work with the basic picture in normal size only). The high resolution window is available and functioning in zoomed-in pictures as well.

Not all the buttons are available in each picture!
