Is there a Firefox plugin to do this…

I want a plugin that will give me the ability to quickly right click an image on a website and with a single click, automatically save it to a folder I specify.

Essentially skip the save location dialog, the download manager, etc. Just right click, click menu option and it auto saves to pre-configured folder.

Is there such a plugin? If so can someone tell me how to get it. I am not an experienced firefox user.
