Deleting Images

Hello,

I am trying to delete several images from the design studio.

When I click on an image listing or thumbnail and go up to the "file actions" menu, it won't let me select "delete." I am only able to delete images one at a time by double clicking to open the image THEN going to "file actions" and selecting "delete." Is this correct? Is there an easier way for me to cleanup my image libaray?

Thanks!
