+
+If you want to download a specific Image/Plate, you can find the path by clicking on the "file paths" icon:

+
+The example shows that the file for this image ([15301_week8_PAS](https://idr.openmicroscopy.org/webclient/?show=image-14788705))can be found at `idr0148-schumacher-kidneytem/20220927-Globus/0000-assay_1-light_microscopy/15301_week8_PAS.tiff`.
