Naw, the eggs and clone Venusaur are stolen from GPX+
The Gardevoir is stolen from Pokefarm and the fusion and mega ones from various people on deviantart.
They didn't even bother to host the images themselves :B
It's (kinda) cool to use the default game sprites, you generally won't get in trouble for that. It's not cool to steal art from other people or sites and use that.
