this does work... but it also requires two very significant points.

1: you must do this wrapping yourself, for everything you wish to simplify, as few libs do it.

2: you now have non-standard error handling and your tools will not warn you if you handle it wrong.

the second one, to me, is borderline fatal for this pattern. You can't look at this code and realize it's missing error handling (or doing it incorrectly), and you can't run `errcheck` to tell you that e.g. you're missing `err := img.Get()`.
