WPClipart: is here to maintain and grow an online collection of artwork for schoolkids and others that is free of
copyright concerns as well as safe from inappropriate images. To ensure these qualities, no direct user-uploaded images are allowed. All artwork is collected/edited or created for use
by me with the
GIMP and some
GIMP extras on
Absolute Linux.
Please email me if you have any questions or concerns. And thanks for stopping by :-)
