Cornice is a cross-platform image viewer written in Python + wxPython + PIL. It doesn't pretend to be complete, fast, or even useful, but I like it and it is the viewer I use on both Linux and Windows. It has been inspired by the famous Windows-only ACDSee.

Here are some key features of "Cornice":

· Fully cross-platform: it should run wherever wxPython does;
· Detail and thumbnail view for images;
· Image preview;
· Automatic recognition of images, with a variety of formats supported;
· Bookmarks;
· Full-screen view;
· Zooming and rotation;
· Slideshow;
· Good keyboard navigation (still not perfect, but this is true for all the features ;-);
· Image loading from zip archives;
· i18n support (with Italian and French translations available);
· EXIF data support;
· Some more...
