2 images side by side and text flowing round images [Solved]

Hi,

I am sure that I am having a Homer Simpson moment here, but, how can I put 2 images side by side in a post. Whenever I try to put in an image block they go one under the other.

I can not also seem to get text to flow around an image - it is simply an image aligned left but with text above and below?

Thanks
Nick
