Make changes to your photos en masse with batch editing.
Often, when you're browsing around Flickr you'll notice a way that someone else is using tags that you could apply to your own photos. For example, you might have tagged several of your photos taken in national parks with the words Yosemite or Yellowstone, but not included the tag national park.
You could browse to each photo's detail page and add the tag manually, or you could take advantage of Flickr's batch-editing features to add the tag to all the relevant photos in one fell swoop.
Batch editing involves making a change to a collection of photos. That collection can be as simple as the first page of your photostream, or a more complex result set based on a multiple-tag search. The key to editing photos in a batch is keeping an eye out for the "Edit as a batch" links.
If you browse to your photostream, you'll see an "Edit these as a batch?" link on the right side of the page. Click the link and you can edit all of the photos on the first page of your photostream at once. You can also gather together a group of photos by tags. Enter a tag (or a group of tags separated by commas) into the "Search by tag" form on your photostream page, and you'll see a list of results like those shown in Figure 5-7.
