In my html I am displaying images as so

<img src="/src/img.jpg" alt="img" onerror="$this.hide();"/>

Is there any way to replicate this functionality in Prince. The alt text is unsightly and I would rather not keep image info in the db.

thanks,
Jake

You can add this CSS rule to your style sheets:

img { content: attr(src, url) }

As a result it will not use the alt attribute as a fallback if the image cannot be loaded.

thanks, that worked. Where could I find documentation for rules like that?

At the moment it's a bit scattered unfortunately, and often requires reference to the CSS specifications. Here is the description of attr syntax in CSS3.
