My two images are:

and

I cant get it to work for the life of me. Can someone jsfiddle or put a working result here showing me how to properly mask the image?

回答1:

You can mask this in Safari and Chrome using the -webkit-mask CSS3 property like so (see fiddle in Safari/Chrome):

<img src="http://i.stack.imgur.com/oJUzS.jpg" 
     style="-webkit-mask:url('http://i.stack.imgur.com/4KEpA.png')" />

However, to do a cross-browser implementation your mask will need alpha transparency in the black section of your .png image and then overlay the mask using CSS position.

Are you trying to achieve this? http://jsfiddle.net/6dRSh/

html

<div id="image"><img src="http://i.stack.imgur.com/oJUzS.jpg">
    <div id="mask"><img src="http://img148.imageshack.us/img148/4645/4kepa.png" ></div>
</div>

css

#image {position:relative;}
#mask {position:absolute; top:0;}
