CSS would be the easiest way. Assign the image a class name (like "leftImage") and then assign it a style of margin-right: 10px;
This CAN be done with pure html, by using tables, or by adding non-breaking character spaces (
, but CSS is a much easier way to go.
If you only have the one image you want to be like this, you can do an inline style, <img src="" style="margin-right:10px"
