Just hot link the image to a host that you have control of instead of uploading it to lemmy. Then you can change the image anytime you like and it won’t be affected by any caching on lemmy.
That is what I have noticed. When I use Catbox, the exact Catbox URL appears on every instance. But when I upload directly to my instance, federated posts use their own cached image instead of the one from my instance.

Oh, does image caching not apply to remotely hosted content? Well, then yeah, that sounds good.

Interesting… thank you for sharing!
It seems caching doesn’t do much, even while also being a big pain for instance admins - so much so that it is explicitly made voluntary.
Perhaps that is why PieFed is going so hard on integration with PixelFed and now Loops.
