I think this is very nice and short
<img src="https://stackoverflow.com/questions/3984287/imagenotfound.gif" alt="Image not found" onerror="this.src="imagefound.gif";" />
But, be careful. The user’s browser will be stuck in an endless loop if the onerror image itself generates an error.
EDIT
To avoid endless loop, remove the onerror
from it at once.
<img src="https://stackoverflow.com/questions/3984287/imagenotfound.gif" alt="Image not found" onerror="this.onerror=null;this.src="imagefound.gif";" />
By calling this.onerror=null
it will remove the onerror then try to get the alternate image.
NEW
I would like to add a jQuery way, if this can help anyone.
<script>
$(document).ready(function()
{
$(".backup_picture").on("error", function(){
$(this).attr('src', './images/nopicture.png');
});
});
</script>
<img class="backup_picture" src="https://stackoverflow.com/questions/3984287/./images/nonexistent_image_file.png" />
You simply need to add class=”backup_picture” to any img tag that you want a backup picture to load if it tries to show a bad image.
