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