* Link: http://code.shishnet.org/shimmie2/ * License: GPLv2 * Description: Show a list of uploaded images * Documentation: * Here is a list of the search methods available out of the box; * Shimmie extensions may provide other filters: * *

Search items can be combined to search for images which match both, * or you can stick "-" in front of an item to search for things that don't * match it. *

Metatags can be followed by ":" rather than "=" if you prefer. *
I.E: "posted:2014-01-01", "id:>=500" etc. *

Some search methods provided by extensions: *
