This plugin is useful to include images in wiki pages with minimal disturbance of the text flow. It's an autonomous plugin, you should be able to use it with any version of Tiki (at least since 1.6). If you want to use it in an old version just copy the file in lib/wiki-plugins/
{CVS(file=>lib/wiki-plugins/wikiplugin_thumb.php)}lib/wiki-plugins/wikiplugin_thumb.php{CVS}
will be transformed in the following thumbnail. Pass your mouse over the thumbnail to get a frame/popup/thing with the full sized image.
Parameters
Mandatory
image : the local path to the image file (won't work with remote files)
Optional
max : indicate the max width or height (whichever is higher) for the thumbnail (default 84)
float : none (default), left or right to make the text run around the thumbnail if wanted
data : it's the special plugin parameter to name what is between the tags. If text is included there, it will be printed over the image. This can be weird, but fun.
