Derek, I just updated this forum with instructions on how to upload an image, here they are:
When making a post or reply there is a button under all the smilie icons that says "Upload MP3" this can be used to upload your images too. Click on this link and a popup window will appear, Browse for your image and click on Upload. Wait for the file to upload, there will be a confirmation when it's complete.
After the upload is complete you have to highlight and copy the link, then click the "Image" link in your post and paste it in to the provided box.
