Proof That Google Discriminates Against Hive Front Ends

The image in the upper left is from my portfolio on PeakD. I used Google's image search to try and find it.

Google shows similar images on the lower part of the screen. When the mouse pointer is hovered above any of those images, the URL of that image shows up in a pop up window like in the image.

What's interesting is that Google can't find my image at all. What this means is most likely that Google's crawlers (bots that go through web pages and index the content) do not index the content (to clarify: I mean the images, I can find blog posts just fine) on Hive front ends at all. I wonder why. Are those sites simply too new? Or what's going on?
