Went to Forum help and it says the following;
In order to add an image to your message or your signature, you must have the image already available on a web server and reachable by a URL. This can be an image on your own personal web page, for example. To place an image within a message, simply use the following Markup Tag:
![[Linked Image]](http://www.example.com/image_name.gif)
For example, if you have an image called cateye.gif and its available from your own website at
http://www.example.com/pics, then you would use the following image markup:
![[Linked Image]](http://www.example.com/pics/cateye.gif)
You can do the same for your signature. Click the My Home option found on any page. Then, under the Your Profile group, click on "Edit Profile". Look for the Signature box, and enter your desired information, including any images/markup as above.
Note: To keep the forums loading quickly for everyone, it is recommended that you do not exceed 35k for your image size.
I don't have a private web page or pictures stored on a server so therein lies my issue!
