Sorry, I am a bit thick, please can someone give me some simple instructions as to how to upload an image, thanks

You need to have the image hosted some where such as Flickr and then right click and copy the image location.
Click the IMG button above the post box (where you are writing) and the below will show up


After the first [img]paste in the image loaction, so that it ssits between the two bracketed boxes.

Preview to check it works and then submit.

look in FAQ section

Can I post images?
Yes, images can be shown in your posts. If the administrator has allowed attachments, you may be able to upload the image to the board. Otherwise, you must link to an image stored on a publicly accessible web server, e.g. http://www.example.com/my-picture.gif. You cannot link to pictures stored on your own PC (unless it is a publicly accessible server) nor images stored behind authentication mechanisms, e.g. hotmail or yahoo mailboxes, password protected sites, etc. To display the image use the BBCode [img] tag.

Thanks, this is what I was trying, but all I get in the preview is a little box with a question mark in, should the actual photo appear in the preview box? Have I missed a space or something somewhere?

Got it, thanks, I was doubling up on some code somewhere.
