Yea you have to get the picture the right size Kev first before you can upload it's on the top bar "my account" then "image gallery" and view/upload images to folder then scroll down to upload image to folder choose image and submit.
If it's to big it tells you and gives you the right size I can remember I think it's 150KB pretty small or you can link it to you picture from your PC hope that helps.
Also choose NEW TOPIC and just Attach a file instead of linking to your folder.
