Downvotes ok? 🙂

What’s too close? I usually hold it about 12 inches from my face

If I self hosted my own Lemmy on my home server, just for myself and I posted / uploaded images on it, when another user from another instance views my image, they cache it, would this mean later down the line if I deleted to free up server space, if someone else on that instance was to come across my image after deletion, because it was previously cached, the image would still show?

Wondering if rolling storage is possible eventually, where an archive of posts older than 2 years is performed and data deleted.
