How can I hide the broken image icon?
Example:

I have an image with error src:
Using CSS only is tough, but you could use CSS's background-image instead of tags...
Something like this:
HTML
CSS
#image {
background-image: url(Error.src);
width: //width of image;
height: //height of image;
}
Here is a working fiddle.
Note: I added the border in the CSS on the fiddle just to demonstrate where the image would be.
