An example of some of the Featured Images you can use to personalize Gmail
Greg Bullock, Software Engineer at Google, said “When we unveiled Gmail’s new look back in November, we introduced a number of new, beautiful HD themes. We also heard that many of you wanted to bring an even more personal touch by setting your own background. So over the next couple of days we are rolling out a new Custom themes section with two options, Light and Dark.”
Since its arrival on the scene back in 2004 Gmail has been constantly updating its feature set in the hope of outdoing webmail alternatives such as AOL Mail, Yahoo! Mail, Hotmail and MobileMe.
The new custom themes feature will roll out to Gmail users over the next few days and can be accessed from within Gmail under Settings > Themes > Custom.
