@unbroken-fighter Click the insert image button:

It's a picture of a tree on the far right of the tools

A dialog pops up asking for the URL (place where the image is stored). Basically if you have an online storage account such as Dropbox, 4 shared etc. you can copy that link and paste it into the 'Image URL' section. If you did it right it the image will show in the box below. Then you add a title and description. Click insert and Resize it with the points that surround the image. :)
