First, make sure that your html file is there, and that you have it in your homepage directory, and that you have the URL of your homepage specified correctly in Netscape.

Then, make sure that the file's permissions are set to 755. To do this, go to your homepage directory, and issue the following command:

  chmod 755 *
  

This will allow everybody to be able to see your homepage. You will need to hit the Reload button in Netscape to make sure that you get the latest version of your page.

Save the file with your editor, and hit the reload button in Netscape. If it doesn't show your changes, there is an error in your html, or you are specifiying the wrong URL.

Check that the file is actually there, that the permissions are set correctly, and that your img tag is formed correctly:

 <img src=scan1.gif>

HTML does not recognize the returns you put in your text. You need to use either the <p> tag, for a paragraph break, or <br> tag for a single break.
