Since the Virtuemart crew changed a lot of code in the latest version of Virtuemart 2 the old Search plugin (wich included the product images) has stopped working. Today We are releasing a new, working versions of these plugins.
The code is modified a lot, as well as the params. This version is not the modified Extended plugin, its the virtuemart simple search plugin with some features for Universal AJAX Live Search. The installer is one file for both Joomla versions.
