Found my images for sale on this site called Crystal Graphics, under their PowerPlugs section. Anyone know anything about them?

I know I didn't contribute the images to them, and since the images are on a number of sites I couldn't identify where they were obtained. But even with an extended license (which none of these have sold for) I don't think they can offer images for print, can they?

And, check out this page. They've won awards, etc.

Is this a rip?

They are partnered with BigStock.

AhHa. Thanks Karin. No complaints, then.
