Hi Greg, some info on this subject: Be aware that icon files (ico) can contain multi-resolution images: 16x16 for browser, 32x32 for desktop (normal icons) and 48x48 for desktop (large icons). And the .png format will NOT support the multi-res functionality.
So I think we could keep all ico files (already generated), and change the favicon used in out pages with the 64x64 (only, sigh) version, and put them in svn. Ah, today I'll generate also the 48x48 version of all images, could be useful. For everything except IE, I use a link reference to call the .png file: <link type="image/png" href="/images/site/favicon.png" rel="icon"> For IE I just dump the .ico file into the root folder, with no reference from the HTML pages themselves. => Interesting trick, maybe we could use it too, keeping also the current favicon.ico but without referencing it. Ok ? Safari for the MAC will not display an updated favicon until the browser cache has been cleared. But choosing ‘empty cache’ from the menu won't help because Safari stores favicons in a separate cache. Go to Edit > Reset Safari, and check “Remove all website icons”. If you can’t find that, you must empty the icon cache yourself. Look for it in User>Library>Safari>Icons. On the Windows version of Safari, find C:\Documents and Settings\YourUserName\Local Settings\Application Data\Apple Computer\Safari\WebpageIcons.db. Quit Safari, delete the file, restart Safari. (Sometimes you need to restart the computer too.) What do you think ? Byeeee
