A simple solution for “image not available” problem
Is there a simple solution for problems with missing or broken images? Yes, it is. You don’t need any script, just an alternate image to display when this problem occur and the “onerror” event available with the img element. Here is an example:
< img src="/path/to/image.jpg" height="100px" width="100px" onerror="this.src = '/path/to/alternate-image.png'" / >
This simple solution was posted by Satya on his web scripting blog. Anyway, if you preffer a more elegant solution, you could use a script that dynamically detects the missing images and replace them with an alternate image. A good Java Script solution is presented on the tech evangelisit’s article.
