Disable mod_pagespeed compression for a specific image file

I'm using Apache with mod_pagespeed. For some reason I can't figure out, mod_pagespeed thinks an image is much smaller than it actually is, which means once the image gets scaled up, it's really blurry.

The image in question is a CSS background-image.

Is there a way to disable mod_pagespeed image compression for a specific file?

Answer

The mod_pagespeed documentation was not clear on this - my impression was that ModPagespeedDisallow only works for URLs containing HTML, but they also seem to work for individual files:

<IfModule pagespeed_module>
    ModPagespeedDisallow "https://www.example.com/assets/image.jpg"
</IfModule>

Put this in apache2's configuration somewhere. We put it in the virtualhost configuration in /etc/apache2/sites-available.
