2 parts:

Part 1, when reading from the search results, images are stretched.
Example: https://education.minecraft.net/support/search_result/?search=server&post-type=knowledgebase

Works fine on https://education.minecraft.net/knowledgebase/how-to-set-up-a-multiplayer-world/

Part 2, clicking the images in the KB links to a broken domain: http://i2.wp.com/education.minecraft.net/wp-content/uploads/2016/07/ip1.png
