Here is a heads up for those who love using themes on Gmail, particularly those HD themes with a high quality image behind the Gmail interface. It’s now possible to use a custom image as a background, thus giving your inbox a personal touch. In the showcase video (embedded below), a number of personalized themes are shown in quick succession, and I have to admit it does look dandy.
Simply click on gear icon on the right and from the menu select Themes. Custom themes are available in two options, Light and Dark. You can upload your own images from the computer, select one from your Google+ photos or simply paste any image URL. If you don't have a particular image in mind, Google provides a rich, searchable gallery of photos to choose from. Try searching for ‘hdr scenery’ or ‘bokeh wallpaper' in the Featured tab.
Custom Themes will be rolled out to all users over the next couple of days.
