Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Substitute feh for the image viewer of your choice. display (part of imagemagick) seems to be a popular choice.

not familiar with the "feh" part of this command?

feh, per its description, is a fast, lightweight image viewer which uses imlib2. It is commandline-driven and supports multiple images through slideshows, thumbnail browsing or multiple windows, and montages or index prints (using TrueType fonts to display file info).

Advanced features include fast dynamic zooming, progressive loading, loading via HTTP (with reload support for watching webcams), recursive file opening (slideshow of a directory hierarchy), and mouse wheel/keyboard control.
