Iconbox icon display

[James McDonald]

I have noticed that the icon box sometimes displays the correct icon of 
running processes and other times it uses a generic icon.

Can anyone let me know:

where I have to save icons
what I need to name the icons
what configuration file changes are needed

In order to have the iconbox display an icon that I dictate for a process.

For example at the moment the xfterm4 shows a generic icon but I would 
like it to display /usr/share/icons/xterm-terminal.png

Thanks...
