Pictures of a purl row and a stitch row?

Hi - I’m just learning to knit and I’d love to find a picture of a row of knit stitches, then a separate picture of a row of purl stitches. Does anyone know where I can see this? Thanks!

Look at the videos here on how to knit and purl. Also Knitting tips http://www.knittinghelp.com/videos/knitting-tips has videos on stockinette, garter, seed and rib stitches.
