Gmail Themes aren't yet compatible with all of Gmail supported browsers. Themes are only available in Internet Explorer 7.0+, Firefox 2.0+ or Safari 3.0+, and Google Chrome. You won't see a 'Themes' tab in your Settings if you're not using the newer version of Gmail on the browsers listed above. Please note that Themes are not available if you're using Internet Explorer 6.0Are Gmail new Themes available only for windws Vista?
No they work on XP also
Make sure your XP does not play Gmail in older version. The themes should work for everyone. If this still doesn't work, sign into Gmail and replace your address bar with

no...i use xp...and theyr working fine
The Themes feature of GMail is based on web technology , it has nothing to do with your Operating System.



So be it Win-XP , Vista or even Linux(any flavor) or Mac OS X , the themes feature should work the same way , provided you are using a web-browser which can handle these web technologies .



Try updating your browser to something like Mozilla 3, IE 7 or Chrome 2. And also check if u have not enabled the basic HTML version of GMail .



And ya , one more thing , to change theme you gotta click on ';Settings'; ( and not options....) and then select the ';themes'; tab .



Keep Enjoyin Google's Gr8 Features

The OS is irrelevant. Works on all operating systems :)
