Found a site called http://www.ogrila.org/ which is basically a site full of starting zone ideas for a possible ogre race =D It's pretty awesome.
But I've found that the page on the history of the ogres has a picture of not just an ogre, but an ogress! of course, it's not an official model, but it's what they'll probably look like if, or hopefully when, blizzard add the female model to the game. they might wait until if (or when =D) they become a playable race like worgen, which gives them a reason to do it. but they should do it anyway, it does make sense!
Link to the page with the picture on: http://www.ogrila.org/ogres.html
They've also got an ogre customiser, which is what it may look like if they become a playable race =D but they have yet to do a female ogre on the customiser, but the male ogre one's quite cool, i find it really cool that the casters have two heads like most ogre magi, shammy or warlocks and everyone else has one head.

Links should all be working now =D the first link had .com and not .org... the rest of them were working (hopefully) anyway
