You can upload images directly to the site without the need for third party hosting.
One of the issues with 3rd party image linking is that unless the other site is secure (https rather than just http) they will not appear on TWW.
To upload an image, click the image icon:
Then when that opens a pop up click the little folder to search your device for an image:
Upload and go!
PS: Try to keep the images small in file size or the server will reject them, less than 1mb please, around 300kb should be good enough though if you can do that.
