Search Comparing Google, Bing, Duck Duck Go, And Yahoo

A friend of mine recently searched google for images of "AllSaints Church NH" and told me they found my image on a phone case, greeting card and pillow , but nothing leading back to prints on FAA. One of the images in the first row that shows up leads to someone else's blog that used my image. Here's the Google link:
https://www.google.com/search?q=all+saints+church+nh&espv=2&biw=1717&bih=872&source=lnms&tbm=isch&sa=X&ei=-ErEVNKuBY_uggTerYJI&ved=0CAcQ_AUoAg#imgdii=_

I did the same exact search on Bing, Duck Duck Go, and Yahoo. All three search engines showed my image with links leading back to FAA for prints, canvas, as well as pillows, and cases. My image leading to the other person's blog was not found either.
Here are the links to the other search engines:
http://www.bing.com/images/search?q=all+saints+church+nh&FORM=HDRSC2#a
https://duckduckgo.com/?q=all+saints+church+nh&iax=1&ia=images
https://images.search.yahoo.com/search/images;_ylt=A0LEVyE8TMRU4pMA9OJXNyoA?p=all+saints+church+nh&fr=yfp-t-304&fr2=piv-web

I've done this search with several other of my images and had the same results. Google simply does NOT pick up any images leading back to my prints for sale on FAA. They will only pick up products.

On the other three search engines, my images show up in the first row leading back to my print sale page as well as the cell phone cases, pillows, and greeting card product pages.

Can anyone explain why this is happening?
