An Email I received recently for a Blogger user complained photos they added to posts were overlapping onto the sidebar.I facet I have seen this on a few blogs and have helped people with the problem.Fixing it is easy and only takes a minute.All we do is add a snippet of Css that makes sure photos and images can only be at maximum 98% the width of posts.So even if you added a huge image this code will restrict it from breaking out of the post body, Lets do it !
 Step 1. - In Your (New Design) Blogger Dashboard Click The Drop Down Menu For Your Blog > Choose Customize > Advanced > Add Css 
 Step 2. Copy and Paste the following code into the Css Section then click Apply To Blog. 
 .post img {max-width:98% !important} 
 That's it, said it was easy.What do you think and have you any other faults on your blog that annoy you ?
