About APNG format: http://en.wikipedia.org/wiki/APNG
This extension animates IMG elements. Also it animates background images/list style images from css styles (div style="…"), but CSS images support may be incomplete.
You can prevent this extension from work on specific domains (Black List mode, default) or allowed it to work ONLY on specific domains (White List mode).

WARNING! CAPTCHA may not work on some sites because of this expansion (it is not always possible to correctly detect captcha images). If captcha does not work on some site, just (temporarily) disable the extension on the it.
