Is there a way to post pics from a cell phone without setting up a webpage that stores pictures?  If not - can pics from FaceBook be shared?

I use Imgur (http://imgur.com/)
It's anonymous and doesn't require an account to post.

Make sure you save the "delete" link once the photo has been uploaded in case you ever want to remove it.

Here's a cell phone pic using photobucket.  

are there instructions for how to do this process?

If you have a smart phone it is very easy. Download the free photobucket app off your app store. Than simply upload your images from your phone onto your photobucket account. Than copy the image link and post it in your post and it will automatically show the picture in your post. Hope this helps.. SS
