I have written and released another WordPress Plugin.
BingImport allows you to import images directly via Bing Search. Besides uploading or hotlinking an image you can go to another tab and perform a Bing Image Search via their API. You can then download the image directly to your server and add the image to the Media Gallery.
If you search a lot of images and you usually search for them online then this plugin could save you a lot of work.
You can download the plugin from http://wordpress.org/extend/plugins/bingimport/ or simply go to add a new plugin in your admin area and search for bingimport.
