Allow customisation of upstream image timeout

[bill-zhanxg]

Goals

Allow loading and optimisation of extremely large image and not just a hard coded 7 seconds

Non-Goals

No response

Background

I'm trying to load extremely large image (20GB) but it throws DOMException {stack: 'TimeoutError: The operation was aborted due t…ss.processTimers (node:internal/timers:529:7)'} after 7 seconds

#65821

Proposal

Add an experimental config in next.config.ts for external image fetching just like the imgOptTimeoutInSeconds option for sharp timeout.

next.js/packages/next/src/server/image-optimizer.ts

Line 568 in 720fe35

signal: AbortSignal.timeout(7_000),
