Thanks again moto,
I've always seen rawbinfo in the WBStartup drawers of OS3.5 and OS3.9, but didn't know it was that which made the simple icon copying possible. It's pretty cool!
@ cecilia
Thanks. So if you see a photo on the Internet that you would like as a PNG icon to use with PowerIcons, how should you proceed? (just briefly) I guess you would have to reduce it to a small size first which is no problem at all.
