Since
this f**king "Geocities" does not support (in fact, allow)

I can not run postcard page here. But, you can send your digital postcards
here.
There are eight images from the cave at that page but with clicking to "Schwarzmooskogel
Eishohle Postcards" link (lover left,blue color) you will access to a gallery
with sixteen images that you can send as postcards from the icecave.
