In this guide: A guide to image pickers, media permission, document selection and reducing accidental access to unrelated personal files.
Important context

User control: Prefer scoped selection where possible should be explained in plain language before a user is expected to make a privacy or permission choice. A permission can often be denied, limited or changed later through browser or Android settings.

Data-minimization principle: Photo and file access: sharing only what a feature needs should use only the information needed for the stated purpose. Users should avoid sharing secrets or unrelated personal information simply because a form, screenshot or upload makes it technically possible.

Prefer scoped selection where possible

Modern platforms can let a user choose specific images instead of granting broad library access.

A product should use the narrowest access model that supports the feature.
