CMS Images preview on main page

[محروم.كوم]

Could anyone send me a link to manual where I could see how does the picture preview on my home page works?

I don't know if I am doing it right. At the moment when I add image between [.img][./img] tags then it displays fine on the main page. But when I add it as an attachment then id doesn't work.

Also - is there a way of setting where the preview image should display on the main page (left, right, top, bottom of the article preview)? __DEFINE_LIKE_SHARE__
