Filter
The filter is a way to filter out pictures based on tags. It's a little more versatile than your average tagging system, though. A filter is made up of tokens. Token types are explained below:
| Token | Action |
|---|---|
| * | Special token describing all pictures |
| tag | Add all pictures with the tag "tag" |
| -tag | Remove all pictures with the tag "tag" |
As you can see, you can filter the pictures in very useful ways. For
example, to see all pictures of campus that don't have cars, put
car -campus. To show all pictures that have nothing to do
with computers, put * -computer. Note that the filter is
parsed left-to-right, so car -campus is not the same as
-campus car.
