Bugger, thanks chaps and sorry about that - so much for that idea. I can't fathom how they hide it from me but not those I share it with. That puts me off the sharing from any other free file hosting companies, it's likely why they supply free file sharing.
I can share from other forums that allow attachments but can't put attachments direct on here.
Could anyone tell me if they get porn when they click the links to an image attachment placed on the two other forums? Or if they can see the image if they are not members of the other forums - or not logged in? It's going to be too cheeky doing it for any more images so its just a curiosity thing really.
