I don't use Jquery.

  
<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>
