Maya Modeling :: How To Open Image File For Reference In Separate Window

I’m a 3DS Max transfer. In 3DS Max there is an option to open an image file for modeling reference in a separate window within Max which always stays on top. This is NOT an image plane to model off of but an IMAGE FILE, a picture i can get the details from that don’t show in a drawing or plane. Currently I open images or groups of images(NOT SEQUENCES) in the default OS file viewer program. This is fine with a dual monitor setup, where I throw the reference images to the other screen. But what about when I’m on my laptop on the go or have no other monitor? Currently I’d have to open the same program, have it underneath MAYA and flip back and forth, which is a very big hassle over time. I’d like to be able to open a small, resizable window WITHIN maya and view the image file(or files!) there so I can move it around my workspace and glance over to it in an instant.

I still want my four panels or all of my panel space to work with. With it being resizable i can even shrink it down to get the gist in the upper right corner where no icons are even zoom in on parts with such a small window.
