Image aline problem in all

I faced to day a problem, I was editing the about us screen and needed insert some images.  First images was lined out to the right no problem. 
but now I wanted a second image two paragraphs down and lined this out left.... en here is the problem this second image is placed directly under the first image. 

I had to edit this directly in html mode to get this right.  I had this before on articles also.
More people who face this problem??
