The easiest way to add photos is to do it from an external source as often you need a web address in some systems. I followed Pieman's instructions on how to use Dropbox and it works an absolute treat and is easy as to use.
What Dropbox does is you save your photos to it, it then gives you a http address. When you use the insert image icon here, you add inside the brackets the http address and voila, you pictures have been inserted. It will work for Facebook, emails, skype and PM's. You can also share photos and give access to your friends to see your photos directly in Dropbox as well. You can save anything to it, word documents etc.
And truly, it is really easy to use.
Do a search for ''Pieman'' and ''Dropbox''. His instructions are really easy to follow. I am really happy with it and thank Pieman for sharing the idea.
