F8-lite theme – image/text alignment problem

I just changed the theme for my photo blog and get an image/text alignment problem.

In a post or page, when I add some text below an image, it’s fine in the editor but the page is displayed with text at the right side of the image. See page below where only the first 2 lines are aligned correctly.

I read dozens of post here and did not find out how to get the text below the image ??

this is how I should appear :

Would appreciate any help 😉
