Art Tools - Pure Ref

I have to say, this is one of my favorite new tools. Here is a quick explanation in their own words.

"PureRef was created to be a simple and lightweight tool for artists to organize and view their reference images. Following is an overview of the features and at the bottom you will find a list of keybinds."

I use it quite often and I've yet to be disappointed. Give it a try! The price is a pay-what-you-want, but trust me on how worthwhile this little piece of software turns out to be.
