you must be indexed or else you could not get traffic from them.
1. you are indexed but you are not searching properly (try as lucy24 suggested), are you hits coming from .com .in etc, search whichever they are coming from
2. your images are indexed in image search (but not your content) and you are gettign clickthroughs from that.
3. your stats program is in error.
