I've reached the Twilight Realm (pretty much the endgame AFAIK) and have only 16 hearts. Considering doing that required me to get something like 30 PoH (just dungeon-crawling with no heart piece hunting only gets you 10 HCs in this game since it trades dungeon-crawling for side-questing), I think that's pretty impressive. However, by my calculations I'm only half done; I'm missing about 20 more PoH if it's possible, like in all other Zeldas, to get to 20 HC.
Anyone know a good resource, with pictures and descriptions, for getting all 50 (!!!) PoH? Obviously I missed a lot.

There is such a guide built into the game. If you go to the fortune teller in Castle Town and ask for Love advice, you will be shown a picture of an as-yet-unclaimed Piece of Heart.
I believe you can ask multiple times in a row without risk of seeing a duplicate; the teller will go through all remaining pieces and then tell you there are no more. I think.
If you see a picture that you absolutely don't recognize from your play through the game, you've probably missed a grotto or secret cave in Hyrule Field. Ride Epona around all the walls and plateaus in the field and look for entrances.
If you must have descriptions, well, err, go to GameFAQs.
