First, thank you for calling me "Dr." My Jewish mother would love it, but actually, I'm an old hippy photographer that has worked mostly in the sciences during my 35 year pro career. However, I only have a BA in photography.
As for using material from my website, yes, feel free to use whatever you need. The correct credit for my photos of the Shroud is: (c)1978 Barrie M. Schwortz
Also, perhaps you could include a link to www.shroud.com on your site so students can go there for further, detailed information.
Good luck with your work.
Warm regards,
Barrie Schwortz
