Multiple photos upload

[muhaimincs]

What if I want to store first the photo(s) taken in component state or async storage and later upload it using promise.all(). I hit this performance error

One of the sources for assign has an enumerable key on the prototype chain. This is an edge case that we do not support. This error is a performance optimization and not spec compliant.
