General information about Linux, very non-specific.
The images on this page have a couple of issues:
- Neither of the images are referenced and as this is a "what is Linux" page, readers will very likely not have a clue why it's there (particularly the GNU image).
- The Tux image is a duplicate of Tux.svg already used on the homepage -- use the SVG and remove the Tux.jpg.
I would recommend using the "thumbs" format for these which would allow a short caption sufficient to provide the reader a reference.
