Creatinga page/post with images and text side by side

Hi

I always seem to struggle (not hard) with images on the left hand side of the page and text along side it.

Is there a plugin out there which helps yuo produce better quality pages, incorporating images more professionally. I dont seem to be able to produce good looking pages, as the text seems to more when you view the page before or after publishing it.

Any tips for a novice.

Thanks
