 over it - but then we'd need to detect the colours used, so that, if it is
 transparent with black text, we only put a white background, or, if it's
 transparent with white text, we only put black, etc.

 That still wouldn't really fix the situation - for example, if the image
 contains different coloured text, i.e black and white, or a light grey,
 it's still going to be an issue.

 Personally, Imgur uses a black-like background, so maybe that would be the
 way to go, to create a standard, but I'm not sure.
