How to call an image with javascript and send if off?

[Blindver]

I am trying to call an img in html and send if off but I can't seem to figure out where I am going wrong. I am sending it off to a <textarea>. (still new at java script)

Here is my HTML

 <div id="buttonWrapper"> <div id="button01"> <img id="buttonImage" src="http://bytes.com/imges/font01.png" alt="button01"> </div> <div id="textArea"> <div id="instruction"> <p> *Type a word here, and click diffrent styles and sizes</p> </div> <div id="textSpot" > <textarea name="word">
 
 
 
Here is my javascript
 
 
    function init(){
        document.querySelectorAll("#buttonImage").onclick = changeFont;
 
 
 
    function changeFont(){
        document.querySelectorAll("word").style.fontFamily = "'Oswald', sans-serif";    
    }
 
}

1) querySelectorAll() returns a NodeList/HTMLCollection, not an HTMLElement (even if there is only one element in the match) on which the defined properties would make sense.

2) "word" is an invalid HTML element.

what you want is querySelector().
