How to make images in articles, pages inline in drupal?

How could I make the main image of an article, basic page or any other custom content type inline as opposed to displaying it separately while the content either stays at the bottom or above the image. I have made a custom content type.

On the blog page single node, the correspodning image is being displayed without any issue as is wrapped by the content. On the other hand, an image on a custom content type single node, it is displayed on a space resrved for this image only. May I know how to get dislayed like it is being on article page.

Thanks and regards
