In this tutorial, I will tell you to make your own custom theme for Google Talk. If you aren’t interested in creating your own theme then you can get unofficial themes from http://www.sravi.com/gtheme/download.html and from http://www.googletalkthemes.com.Let us start with the Gtalk appearance customization:

  2. Create a new folder and name it gtricks.
  3. Let us choose theme ClassicPicture because of its simplicity. Go inside the folder ClassicPicture and you will find another folder named Contents. Copy it.
  4. Navigate back to gtricks folder. Paste the Contents folder inside gtricks folder.
  5. You will discover folder named Resources inside Contents. And inside Resources you will find few more files like main.css, status.html and others.
