RefViewer

RefViewer is a robust image viewer designed to assist artists and developers alike in their workflow.

• Keep your reference images where you can see them
• Flip, rotate, crop, or modify your references on the fly
• Pick a color, or generate a palette when you need to
• Configure your settings to fit your workflow

Since this software is still in development, free bugs are included, if you're into that sort of thing.
