Why images URL is coming this way http://i2.wp.com/www.zomidaily.org/wp-content/uploads/00kualalumpur.jpg?resize=100%2C100? Are you using any resizing plugn? Also I am getting different image markup for every images. Some have this:
<img width="100" height="100" sizes="(max-width: 100px) 100vw, 100px" srcset="http://i0.wp.com/www.zomidaily.org/wp-content/uploads/00deihtung.jpg?resize=100%2C100 100w, http://i0.wp.com/www.zomidaily.org/wp-content/uploads/00deihtung.jpg?w=200 200w" itemprop="image" alt="00deihtung" class="entry-image attachment-post" src="http://i0.wp.com/www.zomidaily.org/wp-content/uploads/00deihtung.jpg?resize=100%2C100">
Another images have this:
<img width="100" height="100" itemprop="image" alt="14aljazeera" class="entry-image attachment-post" src="http://i0.wp.com/www.zomidaily.org/wp-content/uploads/2016/01/14aljazeera.jpg?resize=100%2C100">
Those images are creating the issue which have 2nd type of code.
