Use Brushes with iCloud for artworks backup

[AM-ia]

Since Dropbox was updated it no longer works in the current version of Brushes Redux. But you can use iCloud which works beautifully.

Message to Brushes Redux developer please update the app so that Dropbox works in this.

You can use iCloud to download on the Brushes Redux app. How do you do this? My dropbox is presently attached to the brushes app. I only see the ability to load up to "iCloud photo sharing".
If I upload the photo it is low res????
