A simple "show/hide transparency" toggle for media with an alpha channel would be a nice standard solution. Defaults for a media repository like Wikimedia Commons could reasonably differ from those for a general reference source like Wikipedia, as typical user intentions are likely different.

We could remove the checker by default (pleasing the reader) and add a button to reveal the transparency. This could be implemented for the File: namespace.
With these comments in mind, I've updated the relevant bug in Bugzilla to focus more on a toggle solution in JavaScript. I don't imagine it'd be very difficult to implement, so I've tagged the bug with the "easy" keyword.
