Remote URLs

Stream OME-ZARR data directly from remote servers without downloading anything.

Opening a Remote Dataset

1. Click Open Image on the landing page
2. Paste an OME-ZARR URL into the URL field
3. Click Load from URL

The viewer streams tiles on demand — only the data you're currently viewing is fetched.

Public Data Sources

The Image Data Resource (IDR) hosts thousands of public microscopy datasets in OME-ZARR format. Browse the IDR, find a dataset, and copy its ZARR URL to open it in Find Nuclei Viewer.

Example URLs:

https://uk1s3.embassy.ebi.ac.uk/idr/zarr/v0.4/idr0079A/idr0079_images.zarr
https://uk1s3.embassy.ebi.ac.uk/idr/zarr/v0.4/idr0001A/2551.zarr

CORS Requirements

Remote servers must have CORS enabled for the viewer to access data. Most public OME-ZARR servers (IDR, BioImage Archive) already support CORS.
