    I don't use Jquery.
    Code:
      
    <script type="text/javascript">
    // http://www.w3schools.com/jsref/jsref_obj_string.asp
    // http://www.w3schools.com/jsref/jsref_obj_regexp.asp
    
    var str = '<img src="" alt=""> text text text';
    
    var re=/<[^>]+>/;
    
    alert(re.test(str)); // true
    
    alert(str.match(re)); // <img src="" alt="">
    
    var s = ' metin metin metin';
    
    var yeni = str.match(re) + s;
    
    alert(yeni); // <img src="" alt=""> metin metin metin
    
    // or
    
    alert(str.indexOf('>') ); //18
    
    var t = str.slice(str.indexOf('>') +1 );
    
    alert(t);  // text text text
    
    var T = ' Burada şimdi başka bir yazı var.';
    
    yeni2 = str.replace(str.slice(str.indexOf('>') +1 ), T);
    
    alert(yeni2);  // <img src="" alt=""> Burada şimdi başka bir yazı var.
    
    </script>
