PnP Page Provisioning Images are not imported in the new provisioned site.

Problem solved! thanks to the great Paolo Pialorsi , who provided us with the solution.
Sharing below the solution in case it can be useful in similar cases:

1) First Export the client side page using the -PersistBrandingFiles attribute.

Export-PnPClientSidePage -Identity "TestPage.aspx" -Out .\single-page.xml -PersistBrandingFiles

2) Convert the xml and related content in an unique file pnp.
Convert-PnPFolderToProvisioningTemplate -Folder .\ -Out c:\temp\single-page.pnp

3) Then connect to target site and apply the page provisioning.

Thanks Carlos for your time, and thank Paolo for the solution!

Cheers,

Alessio
