[Inkscape-user] thumbnail to full size.

The following web page has a feature whereby if the mouse hovers over a thumbnail illustration it expands to a full size representation. when one moves the mouse off the particular illo it reverts to thumbnail again. The function uses a javascript program called: oodomimagerollover.js The web page is: http://wexfordpress.com/illos.html

I like to experiment with using svg programs instead of html programs for web pages. Is this thumbnail to full size and back again effect available via Inkscape, either with a hover or a mouse click?
