What are the Usage Rights of Images in the Explore tool in google?

For those unaware, the Research tool in google docs is being replaced by the Explore tool.  It is a fancy change and a cleaner look, but I have had some questions.  I work with teachers on technology integration and I have taught, through the research tool, how to change the usage rights of images.  Now that is gone.  What to do?

I have been trying to figure it out through Google help forum, through twitter, and through countless searching.  I finally found it by playing with the tool.


1. Open the Explore tool, search for 
something, and flip it to images.

2. Hover over an image and 

click the zoom symbol.
