Let me say first, that you should not use GIF files unless you absolutely need their animation capabilities. Why? Because 8bit PNG files are smaller file size (especially after being run through PNGOUT) and they look much better than GIF. GIF files are very outdated, big and look bad.
That said, there may be times when a site you’re redesigning or helping a client with uses GIF files. And sometimes they don’t have the resources to change the code (not just the HTML) to use PNG files. You can still use PNG files but name them with the “.gif” extension. I know may be confusing. But in some cases where its needed as a band aid, the PNG file with a GIF extension will render AOK in IE6, IE7, FF3, Safari and Chrome.

At PDC last week Microsoft announced a little detail; Right clicks will be treated as a first class citizens in Windows 7. How long before you think we’ll see right click used more often on the web (or will it ever happen)? I know some web apps that do use right clicking (and it frustrates the heck out of me, since I loose the browser right click menu!).
