Guitar chord images are all over the internet, remember though that there are many ways to play the same chord and give it a unique sound.
A picture is worth a thousand words. It's easier to use a diagram than read the notes and figure out what fingers to use.
This page is actually an index page for the many different chord images.
Here is a page with major chord images. These get a lot of play time.

These chords have a raised 5th in them and are also useful in line progressions where you hear the bass note raise or lower by one note. It adds a little tension and leads the progression to the next chord.
I hope you found this page useful.
