Difference between P/E and Yield?

[LeoSayer]

Can someone explain to me the difference between yield and price/earnings ratio? Take this example of Lloyds TSB….

I understand that p/e is Current price/EPS and that yield is Price/dividends but they are different and I don't understand why. I guess I’m asking what is the difference between dividends and EPS.

I want to know how to estimate the income I will receive from buying a stock.
