Changes for this year:
Sub pages will no longer have the word "image", I guess it will just
be assumed that the link is an image....
Photometry reference images will now be stored in
sn < year > /reference
I will now post PNG and PDF files (I started last year, but didn't announce it)
Tenth year doing this....
