Lorne, Safari is my chosen browser! and the ExifExt Safari extension allowed me to look at the exif data of any photo displayed in the forums that I use. for instance you may post a photo in NG and with ExifExt i would be able to look at the exif of that photo, I like doing this out of curiosity, as I like to see how others set their cameras and what lenses they are using as I may learn something new or interesting!
I sent an email to the creator of ExifExt and he replied that something he used to access the data was down and that impacted the operation of ExifExt!
