My pictures or posts on RapidBlog are way down the page

Blogger or some themes will sometimes insert css that forces images or pictures very far down the page (below the sidebar). To fix this try inserting some custom CSS

.blog-entry-comments { clear :none !important; }

and/or

.separator { clear: none !important; }

and/or (if you use disqus)

#dsq-comments-title { clear: none !important ;}

.dsq-options { clear:none !important; }

Finally if you use the addthis widget it can sometimes cause problems -- you can also add this custom css

.addthis_default_style { height: 50px !important; }
