With more than 5 million active users as of the time of publication, it's a safe bet to guess that a great majority of Internet users have seen the blue and white Facebook logo a time or two. Since the white Facebook "F" is so pervasive, you won't have any trouble finding a version of the image to copy for marketing or other purposes. Whether you want to use the logo to attract people to your Facebook page from your website or use it to print as part of a poster or other marketing materials, it takes just a few seconds to put a Facebook logo on a screen on your computer.
Navigate to a site that features Facebook icons, such as FaceBookIcons.net or Iconspedia's Facebook page. (see Resources) You can also use Facebook's "Photos and Screenshots" page to view a few limited logos right from Facebook. Scroll through the various Facebook icons to see the selection.
Right-click on the Facebook logo you want to use, and select "Copy" or "Copy Image." (If you're a Mac user, Ctrl-click then select "Copy Image.") If you want the logo available for later use or for uploading to a website or other program, select "Save As" instead of "Copy" and save the file to your computer.
Open the document where you want the Facebook icon to appear.
Place your cursor or click your mouse pointer in the area you wish to display the Facebook logo, and click "Paste." If you want to use the logo not in a document (such as Word) but instead on a Web page sidebar or other website feature, place your cursor in the desired place, select "Upload Image" from the page's menu, select the logo from the folder in which you saved the logo, and click "Upload." This should cause your Facebook logo to appear where you left your cursor.
