WP O Matic Image Problem

Wp O Matic works fine for me however there is one small problem. When It makes a post on my blog, it shows all images in the post correctly on the homepage but not in categories.

For example I grabbed wallpaper using wp o matic. I can see all grabbed wallpaper images on the homepage. But when I click the category “wallpaper” try to see all posts in that particular category I can only see text but not the images.

Would you please advice me how I fix this thing.
