Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Summary

-moz-force-broken-image-icon is an extended CSS property. The value 1 forces a broken image icon even if the image has an alt attribute. When the value 0 is used the image will act as usual and only display the alt attribute.

Note: Even if the value is set to 1 the alt attribute will still be displayed. More information is available below.
