I have been using lightbox successfully using the meta="true" attribute to show EXIF data. This worked very well when saving files from Photoshop CS2 (save as not save for web).
I've just uploaded files saved from CS5 and none of the EXIF data appears. I believe that Photoshop no longer saves JFIF data and only EXIF, but am not now sure whether this is photoshop's fault or Lighbox Gallery's fault for not being able to read the correct data.
Any help would be much appreciated.
