This tip involves replacing the image that displays on Safari's error page. The default Safari compass icon can be changed to whatever you like.

The image I use is a small portrait of Homer Simpson. If you want to use it, download it here. Unzip the file.

(If you prefer to use your own creation, it needs to be named "error-page-icon.tif", saved as a TIFF file with .tif extension, and it should have either a white or a transparent background.)

In your Applications folder, Control-click (right-click for those with a 2-button mouse) on Safari and choose "Show Package Contents".

Drill down through the 'Contents' folder and open the folder marked 'Resources'. Drop the unzipped file into the 'Resources' folder.

When the Finder asks you if you want to replace the already-existing file, simply click on 'Replace'.

Close the window and run Safari. The next time an error occurs you should get your first view of your custom icon.

To test it you can type in a non-working link such as http://woksrule.com.
