Flickr Photo Featured in Other's Website

I was browsing through the Internet search engine and was surprised to stumbled to the below websites.

So what's with these websites? Well, probably it's not something to really go hu-ha all about, but I guess it does consider something big to me. My Flickr photos are featured in three different websites and I did not realized till I was going through the search engine.

First site is in the official Atomium's website http://www.atomium.be/Photos.aspx

A picture of my visit to Atomium in Brussels, Belgium was chosen to be part of newly setup website.

Second is some of the pictures from my recent visit to Hat Yai, Thailand. I came to realized there is a website featuring my flickr picture.

Last but not least, is a picture of my home-made wedding topper of a bride and groom sitting on a 3-tier cupcakes stand.
