Links with an image as source are not Clickable

When activated rightclick does not work as promised. So far, so good.
But the problem is that links (pages of the same site, or from another site) where an image is source in stead of normal text, the link is not longer clickable.

When deactivated, all works well.

For convenience of the visistors the plugin is now deactivated.
