Use Your Background Photo to Tell More About Your Interests
I'm a journalist and run my own website, so of course I put the logo for my business as my background image. But even if you don't own your own business, you should do something similar. Your background photo is a chance to tell others more about what you do and what you're interested in. If you're a writer, use a cool photo of a retro typewriter. Love to sing? How about a collage of vinyl records? Love to cook? Slap on an image of a dish you recently made. Whatever you choose, make sure it's easy to understand and relative to your career goals.
