Hello @yurenchen000 ,

An image viewer is already planned (and included) in HedgeDoc 2. You can test it out on https://hedgedoc.dev/n/features .
We won't add it to the HedgeDoc 1 code base because it is in maintenance only mode

[ErikMichelson]

As this is already included in the current development state of HedgeDoc 2, I'm going to close this issue.
If you want to request more image viewer features (like those from viewer.js), please open an issue in the frontend issue tracker.
