Can I Use GIMP Images from GIMP web site?

["lowes.jennifer" <lowes.jennifer@xxxxxxxxx>]

Greetings!

GIMP is incredible and I am surprised why people haven't discovered it
yet. I would like to start marketing and selling it on EBAY. I prefer
using the professional images located in this page:

http://gimp.org/features/

Can I do this? Or do I have to get personal permission from the author
of of these photos? If the latter, whom do I contact?

To further make my question clear, I would like to do what this guy on
EBAY did:

Thanks,
Jenn
