[Clipart] Posibility of GPL

[Jose Hevia]

I saw recently at gnome-look.org the "Etiquete icons -svg" posted as 
GPL, but posted a "much more complete set" at Openclipart as PD (????). 
I don't know if it was what the author wanted to do.

I have in my hard disk my own KDE icon theme ,they are GPL,and very big 
(2 megs of SVG),but I don't want to realease it as PD,so it will be in 
my hard disk until I found a site to post.
[Sorry , I just don't want Microsoft/Sun(whatever company you want)  to 
complete my/our effort and take credit for that,this is posible with 
PD.]

Is there any possibility to include something with GPL license at 
Openclipart?
