Just so everyone is made aware, Dr. James Tabor just sent me the following note in the comments:

All the photos that Chris and our other consultants have been using are being posted on thejesusdiscovery.org web site just as soon as possible. They show the inscription from all angles, lighting, and various distances so I hope this will help resolve the matter of the disputed iota/zeta or the iota that Chris thinks is an epsilon. I remain convinced that our initial reading of the letters stands. I look forward to hearing from others.

Stay tuned …
