Have you looked at a friends Gmail inbox and seen a nice/interesting background image? Do you want to get away from the boring white background of GMail and spruce up your screen? Let's face it, a lot of us spend way more time looking at our inbox screen than we would like. Shouldn't what we are looking at appeal to us? Well the good news is that it is very easy to change the background theme of your inbox.
Here is how...
Step 1: Click on the settings gear in the top right corner of your Gmail inbox.
Step 2: Select Themes from the drop down menu.
Step 3: Choose the Theme that fits your style, or create your own custom theme (more on that later).
All Done! No saving required. When you select your theme it will automatically change.
