Hello,

Thank you for reviewing my app.
1. This implementation requires to ask permission from this page https://cors-anywhere.herokuapp.com/ which is a simple proxy server for appropriate CORS implementation to make unsplash images editable and exportable from canvas. Just one click on a button.
2. Edited images are not saved to remote server, nor on own filsystem. Instead the local path on client computer is saved along edited text.
