Do you want them on your photo area or to post them like here?
First off if you are going to put them in your photo area on your page Like where you have the word video up there on the top on the left side you should have photo there you might have to change your page settings around to get the photo area once you I am not sure how you got video's and not photo's. I do not have videos I just have photo's and photo albums anyway not to loose you here but once you got photo on your page you need to click on photo then it will take you there and click on add then a symbol of a camera will pop up click on it that will take you to your desktop then click on the one you want then click on the word open which will be on the lower right hand corner of your computer then click on upload then it will ask you to save it click on save and it is in there.
now if you just wanted to post them like on a discussion then up above in these little boxes you have the word link the symbol next to the word link click on that will take you to desktop then after it is uploaded click o.k. then click on add comment and pic shall appear I hope this helps if not let me know.
