Rated 4 out of 5 stars

I like the new look but becouse of your plugin people can choose which is always good thing. What I been missing is chessboard kind of background which makes easier to see alpha of image. Can you make chessboard option and/or custom background image option?

This review is for a previous version of the add-on (1.0.1-signed). 

There's a review from ForkliftFred2K two weeks ago that mentions "Pic Style - Checkerboard" that does exactly that.

Bad news: it's not compatible with version 2.0. Good news: I essentially integrated it in 2.0, since all it took was a bit of extra CSS. If all you want is the checkerboard though, go with Pic Style.
