ELI5 was a mistake. ELI12 would have made much more sense. ELI5 is so obviously absurd that people seem to subconsciously just discard the criterion and put all sorts of things in that no conceivable 5-year-olds would understand, not even the genius ones we occasionally read about. ELI5 is extremely restrictive. ELI12 would be much more sensible. An ELI12 explanation would be possible, but it wouldn't be able to casually assume "frequency domain" or related concepts are things that could be assumed; it would first have to show how you can break images down into frequency components.

I think a smart 12 year old would understand the intuition that fast changing and high frequencies are somehow related, I mean physics gives plenty of concrete example. And then you explain that for images, contours are fast changing, and you have the justification for Fourier coefficients truncation ~ compression. Explaining how DCT helps instead of DFT is the harder part.
