Package failed after upgrading React to 16.x

[EliasC10]

I upgraded React from 15.x to 16.x today. Is it possible to use this package with React 16.x ?
Im using React with Meteor and i get this Error when i try to Import the ImageHelper:

SyntaxError: import declarations may only appear at top level of a module

and a warning that i need React 15.x:

react-preload@0.6.0 requires a peer of react@^15.0.0 but none is installed.

Uncaught SyntaxError: Cannot use import statement outside a module
