I have had some disappear from listings. But what's worse is that they are multiplying in the GHL media storage areas - there are over 300 copies of some images that I uploaded yesterday. The Media storage area won't show any more so as far as I know it could be in to the thousands by now. I submitted a support ticket, but didn't get any acknowledgement ... so just in case you didn't get it, I'm putting it in here too.
