Hello Listers,

Is there not this way to change an icon with gimp ?
Do not delete the old icon.
after changing the old icon with gimp into an new icon,
right-click on the old icon then and open it with an editor of your choice.
In the editor you can see the entries of this icon.
Copy these entries and paste them into the attributes of the new icon.
(you need to right-click on the new icon too, and open it with an editor.
you see then that there the entries are missing. copy and paste the old 
into the attribute-window of the new icon).

That is all, or not ?
