Hi,
Well, it depends where and how you want the text to wrap, but in general you place the image inside a paragraph with the text and set the image to align according to your needs.
Example:
<p><img align=left alt="" src="my image">This is my text which will wrap the image. And so on. And so on.</p>
Positioning the image tag within the text will cause the image to locate just after the line where it was placed.
