In order to view the DjVu images it is necessary to download the DjVu Plug-in. It is worth noting that DjVu allows to improve the picture display quality (by choosing Help from the right button pop-up menu, then Preferences and Color Correction), and to magnify the part of the image. To use the magnifying glass functionality keep the Shift key pressed while moving the mouse cursor on the image (if the Ctrl key is selected as a “hot key” in Hyperlink Preferences of the option Display in Preferences, to show all hyperlinks on the page) or the Ctrl key (if the Shift key is selected).
