To have the text beside the image you have to use the "align" information. Once it knows the image is to the left, for example (could be right or center), then the text can wrap around it. Otherwise it stay below it.

On my eBay listings I put photos each a cell in a table so they stay put and I don't need to worry about odd wrapping between photos. Then you the same thing, "align" the table left or right (and make a given width, don't let it go to 100% or there is no room for text to wrap).
