answer:Create an image you want in a graphics editor. If it’s a simple button with no continuous tones, reduce colors to 16 colors and save it as a GIF file. If it has continuous colors (as photos and watercolor paintings usually do) save it as a JPG at no more than 96 nor less than 72DPI. To add your button to a page, you need to wrap it in a link to Windows Live Messenger, then use HTML and CSS to position it on the page. You’ll need to upload your graphic to your server, making sure the <img src…> uses the correct addressing to reference its location, and modify your page to include the required HTML.
