And I got result as

But I need like this

A:

It's not a case of adding images side by side, you just manually select the images you want to display in your static block and force them to stand next to eachother with CSS
if you have put a div around your images you can do something like:
#divname img{float:left;}

But you have to provide more code for me to know what CSS rule you should use
