Question

I'm using the FilePicker control in an SPFX to prompt the user to select an image - which will appear in the SharePoint page as part of the same webpart.

One of the FilePicker options is for the user to upload a file - and this is what my question relates to. For a modern SharePoint page - is there a best practice way of saving an image in the correct place? It looks like the built in webparts store their images in a Site Assets/SitePages/.../ folder (but it seems there may need to be some associated management with the sub-folder, which is dependent on the page name, and may even change if the page is renamed?).

Just wondered if there was a library, package or API which deals with saving an uploaded image, filing it in the right place and returning the Url. Or, do I have to come up with my own code for this?

Any guidance would be appreciated! Thanks,.

The question concerns the FilePicker control in an SPFx web part and image storage in SharePoint Site Assets/SitePages. Start by reviewing the existing FilePicker upload behavior and the SharePoint APIs or packages available for storing files and returning URLs. Done would be clear guidance on the recommended storage location and whether an existing library handles it.
