HTML IMG Tag - Default Image

To set "default image" in <img> you need to create javascript onerror event. onerror is triggered when an image cannot be displayed for whatever reason:

<img src="http://www.domain.com/image.jpg" onerror="this.src='/error.gif'" />

Easy.

There is a very easy CSS trick to remove that little border:

a { outline: none; }

Now, you try and see :)
