Some images not showing, something missing

I think it’s something related to the thumbnails. I have changed my theme to accentbox and it’s the same.

Actually forget it..I was too exhausted and didn’t see the option ??

Hi.. I have the same problem too.. Is there any help?

On the main page if the image doesn’t show you must set it as a featured image, and if you want it to show it on the post also you must use insert into post.

So you must put it 2 times, depending on the theme.
