I do agree that you should take a different view when it's up to photo and video.
For photos I still recommend the "only" freebie Faststone image viewer. Can do the hole job, incl. batch jobs and is relatively easy to use.


As for video editing, you also should assume a readiness for a steeper learning curve, as those "able" programs aren't "light" stuff. And IMO there are not so many mid-range and still easy-to-use products available. The Abobe sort of things often drive toward overkill, what makes them not easier to use.
