Picture Positions in OceanWide Theme

We changed our Blog to the OceanWide theme from the 133-Theme Pack. Althoug anything looks very fine and the theme gives us a freshness for our blog we have some issues with positioning of the pictures in the blog. They seem to be randomly positioned on the page. Up to some point this would not be an issue but sometimes the reader cannot imagine anymore which text belongs to which picture.
The same with smilies within comments: They are positioned randomly within the line which makes a problem in the comments.

Any help kindly appreciated.
Best regards
