I have learned how to change the untitled document to a title in the browser tab when using the my index.html frames website. I have a default livejournal icon and would like to replace it with another image or delete it. How would i go about doing that?
The livejournal "icon" that you're referring to is commonly known as a 'favicon' and is generated from an icon file in your web directory (or an image directory which is referenced by the metatag(s) for the favicon in your webpage(s)).
If you click the link I provided above you will see a 'how to' related to favicons that might help you sort out:

Hope that helps :) Please remember to mark your thread solved once your issue is resolved.
