I checked. I used images from my article and Basis website which I posted in the end of this article :)

Oh great! If you could do us a huge favor and just note that on your post it would help us a lot. We try to combat plagiarism as much as possible but it is time consuming to have to go digging through the hundreds of submissions we get everyday. Even if they're open source images it helps if their sourced. To make it look cleaner on your posts you can type it this way:
[Source, Pictures, whatever word you want to use](actual link to where you got them)

Okay, I will do it :)
