This plugin scales images on the page dynamically using JavaScript. This includes images generated and used by Connections. One reported negative side effect is that this plugin will scale images so that there appear at only about 5% of their scale. Basically this means it makes the images in Connections appear very small. The only known solution is to deactivate this plugin.
