image won't display at my page via function in ng-repeat

Question

I would like to display images in text instead of :) symbols. I have an html + angularjs 14.8. page with code:

<tr ng-repeat="message in messages | filter:searchForMessage" my-directive="message">
    <td align="left" ng-class='{sent :message.id_user_sent == hiddenFriendId, recieved: message.id_user_sent != hiddenFriendId}'>
            {{message.id_user_sent == hiddenFriendId ? "&#x21FD" : "&#x21D2"}} {{emoji(message.message)}}
    </td>

and I got a function emoji to convert :) to image:

$scope.emoji = function(text) {
var getUrlToMessages = "http://"+location.hostname+(location.port ? ':'+location.port: '')+"/";
var emoticons = {
        ':)'  : getUrlToMessages +'img_smile.png',
        ':('  : getUrlToMessages +'img_sad.png',
        ':D'  : getUrlToMessages +'img_haha.png',
        ':o'  : getUrlToMessages +'img_omg.png'
      }, patterns = [], metachars = /[[\]{}()*+?.\\|^$\-,&#\s]/g;
  // build a regex pattern for each defined property
  for (var i in emoticons) {
      if (emoticons.hasOwnProperty(i)){ // escape metacharacters
          patterns.push('('+i.replace(metachars, "\\$&")+')');
      }
  }
  // build the regular expression and replace
  return text.replace(new RegExp(patterns.join('|'),'g'), function (match) {
      return typeof emoticons[match] != 'undefined' ?'<img ng-src="'+emoticons[match]+'"/>' : match;
  });
}

the problem is that I have no image as an output in my UI - I got a text only:

<img src="http://192.168.169.1:8182/ChatGUINoSQL/messages/img_smile.png"/>

which looks like a proper tag at UI, but this is a text only (cause it changes < and > symbols to the code).

What should I do to see images instead of this URL text? Thank you!

Fix

Add:

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.8/angular-resource.min.js"></script>
<script src="angular-sanitize.min.js"></script>

Update html:

<tr ng-repeat="message in messages | filter:searchForMessage">
    <td align="left" ng-class='{sent :message.id_user_sent == hiddenFriendId, recieved: message.id_user_sent != hiddenFriendId}'>
    {{message.id_user_sent == hiddenFriendId ? "&#x21FD" : "&#x21D2"}} <div ng-bind-html="emoji(message.message)"></div> <!-- {{ message.message }}  -->
    </td>

js updated:

// build the regular expression and replace
  return text.replace(new RegExp(patterns.join('|'), 'g'), function (match) {
    var escape = typeof emoticons[match] != 'undefined' ? '<img src="' + emoticons[match] + '" />' : match;
    return  $sce.trustAsHtml(escape);
  });

Add ngSanitize cdn to your app.

 angular.module('myApp', ['ngSanitize'])// your app

inject in controller

 myApp.controller('MyCtrl', function($scope,$sce) { // your controller

update return statement. Lets mark the html safe to display. $sce

return text.replace(new RegExp(patterns.join('|'), 'g'), function (match) {
    var escape = typeof emoticons[match] != 'undefined' ? '<img src="' + emoticons[match] + '" />' : match;
    return  $sce.trustAsHtml(escape);
});

update html

<div ng-bind-html="emoji(message.message)"></div>
