nextjs - 💡(How to fix) Fix next/image in dev can keep showing stale local image after editing same file until `.next` is deleted and dev server restarted

Link to the code that reproduces this issue

https://github.com/Austin1serb/next.js-minimal-build

To Reproduce

1. Clone the reproduction repo.
2. Install dependencies.
3. Start the app in development mode with next dev.
4. Open the page in the browser.
5. Observe that the page renders the same local image twice: once with next/image and once with a plain <img>.
6. Edit the source image file used by both elements without changing its filename. For example, crop it or apply a visible filter.
7. Refresh the page.
8. Observe that the plain <img> reflects the updated image, but next/image continues showing the old version.
9. Rename the image file or delete .next and restart the dev server.
10. Observe that next/image then shows the updated image.

Current vs. Expected behavior

Following the steps above, I expect both next/image and plain <img> to reflect the updated local file in development after the image contents change.

Instead, only the plain <img> updates. next/image continues to show a stale version of the image when the file contents change but the filename stays the same.

In my testing:

• plain <img> updates correctly
• next/image stays stale
• renaming the image file fixes it
• deleting .next and restarting next dev also fixes it

This makes it look like development mode is not invalidating cached or optimized output for a changed local image when the path remains unchanged.

Provide environment information

Please run `next info` in the reproduction repo and replace this block with the output.

next dev

Additional context

This is specifically about local development.

The reproduction demonstrates a difference between next/image and a plain <img> using the same local source image:

• next/image does not update after editing the image file if the filename stays the same
• plain <img> does update

Workarounds:

• rename the image file
• delete .next and restart the dev server

I have not yet bisected canary versions to identify the first version where this started.
