You can't send attachments to the listserv, so your photos did not come through. I recommend uploading photos and other attachments to WeTransfer, sending them to yourself. When WeTransfer sends you the download link for the files, you can include the link in your email to the list, so anyone on the list can get them. 

Best,
Gary

 Here are two examples of Agfa PEM 469 taken a few years back, as you can
