I would like to add two suggestions to this list as they seem to fit here. Command line is usable, but not user friendly. There is already the Exiv2 tool I mentioned as well as the ExifTool Perl Module ( ). It will also be important that this functionality can be reached through a GUI. and Adobe are really pushing with XMP metadata in images. Everyone is tagging their web content with keywords. Look at the current state of the web with social bookmarking, tagging, and folksonomy websites. I feel this type of feature will go along way to making XnView more popular. The project may help you with many of your Exif and IPTC needs for XnView. With each directory, a person could either manually enter in the fields they want to change, our point it to a template batch job file. Specifically, I would like to be able to have XnView run through a directory and subdirectories, grab all JPG's for the first directory, edit (or append) specific IPTC and EXIF data, keep all other IPTC and EXIF data intact, then move on to the next directory. It just needs to be extended and polished. Xnveiw has the potential to be the perfect tool to be able to manage this metadata because you already have batch capabilities and some IPTC / Exif functionality. With 20,000 images this will take a long time. We use Google Picasa and other tools to search for the photos.Д¬urrently we are using Picasa to create the Keywords and Caption/Description fields for each image. We are moving away from folder organization and using IPTC/EXIF/XMP to 'organize' our photos. Our images grown by about 4,000 per year. Myself and some friends need to manage 20,000+ images.
