WTF???
Loking at the page, I noticed the two images on the right of that one were mine and are also introduced as "Hubble Images". Browsing through the "catalog" I saw at least 5 other of my images, none of them properly credited. I also saw at least 10 other images that I recognized from other friends, again credited as Hubble images, and I only browsed for a bit. I could be wrong, but my guess is they're fetching all APOD images, credit them as Hubble, and collect their Google adSense check every month. This is not a single case of image abuse, it's complete disregard for other people's work in a larger scale.
