Wrap text around images

How can i make text wrap around an image?
I know how to setup my CSS for this (float) but since redactor keeps wrapping images in

tags this cant work.
Also R3 wont let me insert an image inside the

tag it wil wrap the before part and the after part of the text inside theyr own

tags. How can i tell Redacot to stop doing that???
Tnx
