There is no need for a secondary source. Just right click on your pictures and you should see the icon for resizing. All the way down to 240 x 380.. After you choose to resize you will see the CE in front of that pic. Those are the ones you want to post. Kinda neat, cause it doesn`t delete the original size pic. Just that now you have 2 of the same. Try it and give feedback if you are having problems with it.
