Okay, it can be done, but not very nicely. You can’t link the picture directly into OBT so it shows up in your post. If you really want to use Facebook you have to click on the picture you want to insert and copy the link at the bootom of the page that says ‘Show people this photo by clicking the link’.
When you have copied the link, paste into an OBT as you would if it was a web address (URL) and not an image. If you get a little white box with a red cross inside after yopu have submitted your post it’s all gone wrong! 
Photobucket is free and easy to get set-up, and if intend on uploading pics in the future it’s the way to go
