If you align your images on your Squarespace site to the right or left the text gets a bit too close.
Insert the following Code to the custom CSS section:

 

CSS Code

.full-image-float-right { margin-left: 30px; margin-top:5px; margin-bottom: 20px; }
.full-image-float-left { margin-right: 30px; margin-top:5px; margin-bottom: 20px; }

/* gives your images when aligned left or right a bit more space */
