Layout of text with images

Hello,
I am following the development of our new site with Drupal, and I would like to solve a simple layout issue.

A problem I have had with Drupal concerning the layout, is that it seems that it doesn't manage a proper layout for images + text, which results in often having the read more • add new comment • Language line facing the image instead of being below it. Look at the bottom of our beta page http://water.bridge-initiative.org/en/overview/ to see what I mean.

How could you overcome this as some sites succeeded ? Which of the two following directions is to be explored ? Have you developed a solution ?

* Coding template to go to the line after the image, if it is longer than the article or its teaser. What could do you use for that ?

* Changing the layout of the image and the layout of the page. I noticed here that the only "align" tags available when you choose an image with the img_assist module from TinyMCE are : right and left, why not top, bottom, as well as middle ? Would this solve the problem, and is there a way to do it ?

Thanks for taking some time to visit our site, and give us a few advice on layout.
