BetterViewer от Adem KOUKI

BetterViewer makes image viewing faster, easier, and more fun.

BetterViewer was designed as a replacement for the image viewing mode built into Firefox and Chrome-based web browsers.

With BetterViewer you can use various keyboard shortcuts to quickly pan, zoom images, edit and a lot more!
