A picture paints a thousand words

hi,
I am looking for the meaning and eplaination about the following quote:
A picture paints a thousand words
Bye

Simply put, it means that a picture will be far more descriptive of something than words can ever be, or, to put it another way, no matter how hard you try, you can't beat a visual presentation.

Having sat through far too many Powerpoint-rich presentations from Microsoft worker ants in my time, I have to entirely disagree. The acolytes of Saint Bill of Seattle manage effortlessly to be meaningless, no matter which medium they choose to present in.
