Hi guys, I stumbled upon a pretty nifty photo image search filter which searches and updates pictures to show when you start to type. Below is the full code to create your own Image search with images feed from Flickr.

jQuery Code for Live Image Search

$("#filter").keyup(function () {
    var filter = $(this).val(), count = 0;
    $(".filtered:first li").each(function () {
        if ($(this).text().search(new RegExp(filter, "i")) Demo

It uses the Live Search with QuickSilver Style jQuery plugin based upon the QuickSilver string ranking algorithm in JavaScript.

Quicksilver Live Search Plugin

[js] (function($) { var self = null; $.fn.liveUpdate = function(list) { return this.each(function() { new $.liveUpdate(this, list); }); }; $.liveUpdate = function (e, list) { this.field = $(e); this.list = $('#' + list); if (this.list.length > 0) { this.init(); } }; $.liveUpdate.prototype = { init: function() { var self = this; this.setupCache(); this.field.parents('form').submit(function() { return false; }); this.field.keyup(function() { self.filter(); }); self.filter(); }, filter: function() { if ($.trim(this.field.val()) == '') { this.list.children('li').show(); return; } this.displayResults(this.getScores(this.field.val().toLowerCase())); }, setupCache: function() { var self = this; this.cache = []; this.rows = []; this.list.children('li').each(function() { self.cache.push(this.innerHTML.toLowerCase()); self.rows.push($(this)); }); this.cache_length = this.cache.length; }, displayResults: function(scores) { var self = this; this.list.children('li').hide(); $.each(scores, function(i, score) { self.rows[score[1]].show(); }); }, getScores: function(term) { var scores = []; for (var i=0; i 0) { scores.push([score, i]); } } return scores.sort(function(a, b) { return b[0] - a[0]; }); } } })(jQuery);
