You've taken the trouble to write a Java applet, so you naturally want everyone to see it. Unfortunately, there are some viewers that still don't have a Java-capable browser or their OS doesn't support Java. When they attempt to load your page, all they will see a gray box. To solve this problem, you can specify an image to display in place of the applet. Use the <IMG> tag inside the <APPLET> tag as shown below:
<APPLET CODEBASE="MyAppletFolder"
CODE=Java.class
WIDTH=100
HEIGHT=200>
<IMG SRC=Alternate.gif ALT="Upgrade to Internet Explorer to view this Java
applet.">
</APPLET>
