Bill,

The list only accepts jpg image attachments, not tiff.

I used the unprocessed backup copy of the message to extract the tiff images
and converted them to jpegs.

After looking at them I was somewhat puzzled as they are at the extreme range
of contrast, almost like a black & white image produced from an engraving.
ImageMagick shows them as being only a 1 bitplane image, black & white colors
only, which explains it! After blowing them into Paint Shop Pro as jpegs I
processed them to sort of enhance the images into a psuedo gray scale, but I
am afraid they aren't like the original photographs. I also reduced them to
1200 pixels wide so most people can view them on their monitors.

Here they are, for what it is worth.
