Image positioning and borders

Hello, 

I would like to reposition my images, so that they can be placed on the sides, and my page content isnt permanently centralized, ive tried to research a solution. I've come across some codes, like below, but nothing has helped so far.

".index-section-wrapper.page-content {max-width:100% !important;}
#content {
 width: 1000px !important;
}"

I would like to have image placement for example website www. pushkinantiques . com

I have attached an example of how I wold like one of my images to be positioned, any help is appreciated, thank you.
