Thanks for coming back to me on this, you can indeed upload a picture, when you reply to this post, there is a bar of icons just above where you type, one of the icons looks like a little picture. If you click on this, you can upload a picture from your PC.
I guess that this is still happening for you then, so I think we should get a technician out to take a look at things for you. I've sent you a private message in order to investigate further, please look to the top left of this page where you'll see a red envelope icon. Click on this and you'll see my message.
