Kako dodati scriptu u WP?

Kako dodati scriptu koja bi trebala biti u pozadini, a pokazivati samo ovo:
E-mail, klikni ovdje…

Evo scripte iz http://www.dynamicdrive.com/emailriddler/index.htm
Evo je dolje:

<script type=”text/javascript”>
/*<![CDATA[*/

/***********************************************
* Encrypt Email script- Please keep notice intact
* Tool URL: http://www.dynamicdrive.com/emailriddler/
* **********************************************/
<!– Encrypted version of: webartng [at] ********.*** //–>

var emailriddlerarray=[119,101,98,97,114,116,110,103,64,119,101,98,97,114,116,110,103,46,99,111,109]
var encryptedemail_id31=” //variable to contain encrypted email
for (var i=0; i<emailriddlerarray.length; i++)
encryptedemail_id31+=String.fromCharCode(emailriddlerarray[i])

document.write(‘E-mail, klikni ovdje…‘)
