  17. 17. New Background Choose one of the designs Twitter provides, or try out Themeleon. If you want to try uploading your own image: Click Choose File to upload your own image.There are lots of companies that provide images for twitter backgrounds. They will even offer to install them for you. BE CAREFUL.
  18. 18. Why not let others see what I’m doing? Websites that offer things like free backgrounds, smilies for chat, toolbars and other extras don’t usually do it because they are nice. Companies exist to make money. Some companies make money honestly, others don’t. Let’s look at one example:  twitrounds.com offers free background pictures for your twitter page.
  19. 19. Yay! Free stuff! I choose my favorite (so cute!): When I click on it, they offer to install it for me:  If I choose this, they will:  send a tweet to all my followers  make my account follow them  send junk mail for other sitesThis site is honest because they at leasttell you directly what they will do.Other sites can be much, much worse.
  20. 20. You Try Change the background of your twitter page. Do It Yourself - don’t let the webpage sign-in for you. You can use themeleon or some other place to find a background (hint: search on google!) Find the one you like, add it, and let me see it. Remember - don’t sign up for anything, and try to not download anything to your computer.
