Not full-width images in blog

Hi, 

I am trying to as one of my essays as blog that includes a figure.  In my essay pdf, I have it as a right-hand side panel with the image (a screenshot of some data, with a figure legend), and the essay text continues on the left. 

In my blog, I see to only be able to have a full width image block. Given the size of the screenshot, this just leaves a load of empty space and looks quite poorly presented, in my opinion. 

Is there a way to insert an image that is just to the side - as in Wrap text, Square in MS Word?  

Thanks, 

Sarah

Use a spacer block, push the image to one side, then add a text block to the side of the image and you should be able to delete the spacer block.
