This is another dumb question about a collection of pictures kept on the web.
Is it possible to search them for the keywords put into the IPTC metadata of photographs in iPhoto [or tags in Picasa]?
Not being a user much of iPhoto or Picasa I can't answer for those but from Photoshop Elements the keywords applied in Information-Description-Keywords do remain with the images when uploaded to picture libraries and are then searchable online. I don't use the IPTC fields.
