For starters: Observer on Wikipedia. It includes examples in Java, Python and C++, and lots of links.
Here is a C# example & UML diagram.

it seems good although have aversion to wikipedia. I am from czech republic and czech wikipedia does not have a lot of informations on specialised problems.

@joseph change to the english version; update the url with en in stead of your country code. But I agree, the default non-english page sucks big time.

@joseph this is the English version. It has very good information about most known design patterns.

Head first design patterns is the book for you.
There are loads of pictures in this book.

Most of the chapter on the Observer pattern from the Design Patterns in Java book can be viewed on Google Books.
Same thing for Head First Design patterns, by the way.
