I'm setting up Kids Corner but it doesn't seem like it will allow me to put photos in there. That's half of what my kid does with my phone. Am I missing something or is it just not an option?
You are not missing anything. I think this was done intentionally so kids won't delete photos and what not. You could probably get around this by getting a third part photo app and then giving them access to that app though most of those apps are photo editing apps so it may mess up your originals though they usually save as a separate file. Alternatively you can allow access to the Skydrive app and then set your photos to auto upload to skydrive. Then they can browse through there but they will see anything else you have on there. If you are trying to give them access to take pictures then just check off the camera app.
