REALLY REALLY new to this . Need to have filenames in big batches written over to IPTC field. I rename all my photos before uploading to a photosharing site : SmugMug. It needs filenames to be in some IPTC field in order for it to make searchable captions for the photos. I was using something called BreezeBrowser before my trial time ran out. You drag/drop your folder of photos onto it , select all, put this thing they called a "token" ( @file@ ) into the correct iptc field ( had to figure out which one, and remember to switch something in preferences, but then... ) presto change-o : all was well. Seems like Image-Exif Tool can do this to ? Bit over my head. Have downloaded and unzipped exiftool 7 23. What would I need to add , write where in order to get something out of it ? Would like to drag folder of photos onto something , have each individual filename written/converted to IPTC field .. so that I could upload to my photo site where the IPTC would get displayed as the captions. I got the impression that there's 2 or three different IPTC fields ( desciption, caption, comment - I think? ) that could get filled in. SmugMug ( staff, forum ) is hopeless in figuring out which is which. Wonder which ? I'm on a PC running vista, pics are jpegs. Any help would be great. Marty (voicelit)
