With this add-on you can easily view if the image you are currently viewing (using right-click menu -> View image) has transparency.
It does this by changing the simple white background that is shown by default by a checkerboard background (similar to the ones used in photo editing software).
Permission explanation: "Access your data for all websites": The add-on checks if the current webpage is a standalone image and if it is, it will inject CSS to add the checkerboard background to the image. In order to check if each webpage is a standalone image, it needs to "access the data" of the websites. No data is read or stored from the websites.

I created this add-on because direct styling with the Stylish add-on no longer worked with 3.5.
The following only applies to versions prior to 2.0: For users that use Stylish I also added 2 class names in the view image page so you can change the styling with ease. These classes are:
picstyle_body - They apply to the page (this is where the background is set)
