Stash supports creating galleries from zip files containing images, but when building the face recognition model, the log fills up with these warning messages:
[Plugin / Local Visage] Image path does not exist and cannot be read: C:\path\to\file.zip\internal\path\to\image.jpg
I think the plugin is likely treating that as a direct path to an image on the file system, and not recognizing there is a zip archive in the middle of the path, that needs to be extracted to get the image
