Click that.
Opens window - find - Easy Photo Upload & Posting Web App! Click that
Have your photos saved in a file folder.
Drag & Drop photo icon to the App - not the actual picture - just the icon

Copy & Paste the address from there to the Post A Reply box where you usually type you posts -
you can put in text and then the link and then more text and then more links or whatever you want.
When you click POST MESSAGE the links will be part of the message and somehow the photos appear.
