Summary:
Hi there,
As ospfranco found there is some documentation for the code coming from #7338 missing, so I added it. It concerns the method, headers and bdoy field on the Image source object.
If you would like to have any changes made, please don't hesitate to comment, I will add them.
Have a nice day and thank you for maintaining React Native!
