Rated 5 out of 5 stars

Brilliant! Best use scenarios for me (so far): facilitates enhanced viewing of for-sale item images on Craigslist and auction sites, ameliorates my art history and photography research, and (BONUS!) delivers a HUGE improvement on a looped .gif of radar imagery provided by the National Weather Service on many of weather.gov's pages.

This review is for a previous version of the add-on (3.6).
