colon before the namespace: [[:Image:imagename]]. Both
versions that can be displayed on wiki pages can be formatted just
like normal links (see Chapter 6.1). To display external images, just
enter the URL of the file in the source text. The wiki software will
recognize it and insert the original image at that spot. Note that a
space must be inserted after the URL; otherwise the end of the address
cannot be detected.

Integrated internal images, in contrast to external pictures, can be
enhanced with a series of formatting commands that are entered with
a vertical line separating them, as in:
[[Image:gaotc1.jpg|thumb|50px|left|Cave1]]
Each of these entries is optional:
� left/right/center/none. Determines the horizontal
alignment of an image. Any existing text is arranged around the
image. For “none,” no text is positioned near the image.
� sizepx. Determines the image width in pixels. The height is
automatically adjusted.
� frame. If this parameter is indicated, the image will be displayed
in its original size with a frame and caption (see below).
Any size information will have no effect. Standard alignment
for the image is along the right margin.
� thumb. The image is displayed as a thumbnail for preview purposes
and includes a symbol which indicates the tooltip text
“enlarge.” Standard alignment for the image is also along the
right margin.
The last parameter contains a description of the image. This description
is displayed as tooltip text when the mouse is rolled over the
image. Texts of this sort are important because they can also be seen
by people with vision impairments who surf using voice output. In
addition, they provide standard users with further information on the
display. In both the “thumb” and the “frame” display modes, the description
is added as a caption. Here, it is also possible to add basic
formats (e.g. bold and italics), as well as links. However, please note
that these formats are translated into HTML code in the normal image
display, and thus will appear as tags in the tooltip text.
