I have seen a lot of people stating they can't post an image on these forums so i am going to try and explain how.
First off you will need a couple of things they are 1) The image to display and 2) an image hosting web site ( I use my own web site and upload my images to display there)
ok
Step 1 ) Start your forum off then click on the insert image button as shown here :-

This will open a Dialog box that you fill in to tell the forum where the image is located
Step 2) The location Dialog box
Fill out the Image URL make sure you get it correct or it won't work if you used upper case letters you must use them etc. Then all you need to do is click on the insert button that is it your image should show up straight away in the forum you are writing.
