Forget the hosting site. You can do it quickly from your own computer. This is my method:
A) From my phone, I email the pictures to myself.
B) Using my computer, I pick up those pics and save them to my "Downloads" or "Picture" file folder.
C) Go to CB site via your computer and make your post. Click on the download pictures feature and browse to where they reside. Transfer the picture to your posting.
Hope this works for you.
