Images shown in pages alongside Adsense and BlogAds…how?

Hey guys,

I own an entertainment magazine/blog called The Daily Buzzer and would like to integrate a little feature to it that is currently used on many entertainment sites:

https://www.popoholic.com/2006/10/26/xbox-360-party-attracts-lindsay-lohan
https://www.egotastic.com/entertainment/celebrities/julia-roberts/no-thats-not-julia-roberts-nipple-001821

If you visit these posts, you can see that clicking on one of the images would lead you to a different path, which then directs to a page that has 3 Adsense blocks & BlogAds and the full-sized image, but the page still looks like it’s within the blog.

How is this done? can anyone guide me?
