I think you need to look around on the internet for a free Web Hosting Service. Signup and they will give you some storage space to work with, next upload your images / pictures to thier new home. Then, when your ready to display the images, simply incude the URL in between the img, /img UBB code.
That should cover it. You might want to go here to start the search, http://www.earnmoney.freehosting.net/Webhosting.htm
