IMAGE HOSTING?

You can use your locker here. Of course, it has a limit as to how much you can host (if you get more MS the amount will increase) but it's still a decent size for pictures only. Just hover over your name on the top bar and click on Locker. Choose to upload and viola~ (You also have the option of flagging files as private. Usually people can browse through your Locker and see what you have, but if you flag something as private they can't see it. Doing so doesn't mess with linking either.)

Another decent place is Imgur (though it can mess up the upload sometimes) or getting a DropBox - gives you 2GB of space for free, though if you want more you have to purchase it. But that much should be fine. Just don't add people to keep it private.

What about Dropbox? Or Microsoft SkyDrive? You get a lot of free space, and both can integrate directly with your computer's filesystem. I have both of those (you get a SkyDrive if you have a hotmail account), and they are handy. Dropbox is super handy for collaboration on projects, too.
