Copy all the images which you have and navigate to >> visual studio select Project>>Properties.There select Resources and paste all copied images on the right side pane.

    Hashtable emotions;
    void CreateEmotions()
    {
        emotions= new Hashtable(6);
        emotions.Add(":-)", Project.Properties.Resources.regular_smile);
        emotions.Add(":)",  Project.Properties.Resources.regular_smile);

    }

    void AddEmotions()
    {
        foreach (string emote in emotions.Keys)
        {
            while(richTextBox1.Text.Contains(emote))
            {
                int ind = richTextBox1.Text.IndexOf(emote);
                richTextBox1.Select(ind, emote.Length);
                Clipboard.SetImage((Image)emotions[emote]);
                richTextBox1.Paste();
            }
        }
    }
