* 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:
*
* - by tag, eg
*
* - cat
*
- pie
*
- somethi* -- wildcards are supported
*
* - size (=, <, >, <=, >=) width x height, eg
*
* - size=1024x768 -- a specific wallpaper size
*
- size>=500x500 -- no small images
*
- size<1000x1000 -- no large images
*
* - ratio (=, <, >, <=, >=) width : height, eg
*
* - ratio=4:3, ratio=16:9 -- standard wallpaper
*
- ratio=1:1 -- square images
*
- ratio<1:1 -- tall images
*
- ratio>1:1 -- wide images
*
* - filesize (=, <, >, <=, >=) size, eg
*
* - filesize>1024 -- no images under 1KB
*
- filesize<=3MB -- shorthand filesizes are supported too
*
* - id (=, <, >, <=, >=) number, eg
*
* - id<20 -- search only the first few images
*
- id>=500 -- search later images
*
* - user=Username, eg
*
* - user=Shish -- find all of Shish's posts
*
* - hash=md5sum, eg
*
* - hash=bf5b59173f16b6937a4021713dbfaa72 -- find the "Taiga want up!" image
*
* - filetype=type, eg
*
* - filetype=png -- find all PNG images
*
* - filename=blah, eg
*
* - filename=kitten -- find all images with "kitten" in the original filename
*
* - posted (=, <, >, <=, >=) date, eg
*
* - posted>=2009-12-25 posted<=2010-01-01 -- find images posted between christmas and new year
*
*
* 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.
*
Some search methods provided by extensions:
*
* - Danbooru API
*
* - md5:[hash] -- same as "hash=", but the API calls it by a different name
*
* - Numeric Score
*
* - score (=, <, >, <=, >=) number -- seach by score
*
- upvoted_by=Username -- search for a user's likes
*
- downvoted_by=Username -- search for a user's dislikes
*
* - Image Rating
*
* - rating=se -- find safe and explicit images, ignore questionable and unknown
*
* - Favorites
*
* - favorites (=, <, >, <=, >=) number -- search for images favourited a certain number of times
*
- favourited_by=Username -- search for a user's choices
*
* - Notes
*
* - notes (=, <, >, <=, >=) number -- search by the number of notes an image has
*
