Full width colored background for watermark – possible?

Hi,
the most beautiful way to apply watermarks automatically is the one I saw at massroots today. They set a colored full-width bar at the bottom of each image. The colored bar is a bit transaprent and they place their logo within it in the right corner.

Is this possible with this plugin?

Thanks!
