Works mostly as advertised. Sadly, because of how Google image search currently works, many things labeled "GIF" are not actual gifs or do not have a usable source provided and can't be animated at this time. Hopefully this will be resolved in the not-to-distant future. Or maybe Google will finally catch up with Bing in that department and do it themselves. :P

Works as expected, just have to click the extension's icon to activate for one use. Or, select "Always allow on www.google.com" for automatic activation

Would be cool if permissions could be reduced a bit. Not sure if its possible, but "www.google.com/search" would be more preferable to "www.google.com/*"
