Merged requested to merge erciccione/monero-site:assets into master
The images i used for 2 blog posts were put on a newly created blog folder in
/img, but we already have a dedicated section where images for blog posts can be put
/blog/assets. I removed the folder
/img/blog and moved its content (the 2 images i added) in dedicated folders in assets. This for consistency with the other blog posts.
