XF 1.5 message preview - uploaded image permission issue


Hi Guys

i've got a small issue, not sure if its config or a bug...

when my users post or reply to a message and upload an image, hit Insert Inline, then preview the message the image doesn't show in the preview window at the top instead you get a link to the attachment: View Attachments XXXXX when you then click this you get a permission error...

should this display as and Image or the text link?
