You might need to create another table or something along those lines to help with this. Try splitting your table cell into 2 columns. Put your text in one of the new cells and put your ad box in the other column. That might help you.
where is the pic in relation to the added text; upper left? right? If I understand your question, selecting "format" and then "position", in FP, you can select one of the available wrapping/positioning styles. I didn't quite like what was available, so ended up using the following tag: (in the image tag, you must specify if you want the img "center", "left", "right" etc) <span class="text">put text here close with </span>
