Thumbnail galleries are a great way to display large amount of images in an organized way, but sometimes the thumbnails are too small and we are looking for a specific image that we can't seem to find. The process can turn quite boring if we have to click to load every one of them to see a full size display... to avoid these situations, this extension will display a dynamic enlarged preview image of each thumbnail as the mouse rools over, while making it dissapear as the mouse rolls out.
