I just wanted to share a tool that I recently rediscovered that is super useful for organizing reference material for paintings. As you probably know, having just one reference is never enough. This tool allows us to create documents that are easy to add to, re-organize and zoom in on. It's a free tool (though I highly recommend you send them a donation for their hard work!) and it has definitely changed the way I work. Now with just a right click, copy and paste you can save all your reference images in one place.
Some of the artists in my ref document. I will hunt down the rest!
