I really like the thumbnail capability.

edit: Never mind, I found the Navigate Up WE extension.
(One thing I would like to see is a way to navigate to the parent directory of the image being viewed to allow choosing another directory.)

Thank you for this extension.

Very nice image viewer, better than most Windows image viewers - load large files faster because it uses firefox.

Others like irfanview, xNview, fastStone, all load big images like Gifs much more slowly than this.

Thanks for the plugin!!

This is precisely what I've been looking for some time now! I wanted an image gallery for Windows but I knew I could get one without having to download a program. There was a problem with the arrows at the beginning, I guess I just had to close and open Firefox because now it works great.
