How to save "uploaded" images to WordPress's server (/wp-content/upload)

Also there are no thumbnails created. Here how it works now https://www.ucarecdn.com/11035a38-acea-46d7-8a2d-ec2f0d5836f3/uploadcarebuggy.png

WordPress 4.3
Uploadcare 2.3.2

Alex,

1. Uploadcare is built to solve problems related to saving and storing files yourself, so in basic use case saving files back to WP is exactly you want to avoid ?? However, we’re going to add this option in future plugin versions.
2. Could you tell me what URLs are those thumbnails are loaded from? Is there anything relevant in JS console?

1. Then there is misleading title of the plugin which states: “Uploadcare: Add media from anywhere“. Nothing about problems of storing files outside a server. We are use watermark applying and some other similar WP plugins to work with uploaded images. There is only problem we want to solve is Add media from anywhere.

2. All thumbnails are loaded from https://our-website.domain/wp-includes/images/media/default.png
After uploading a file there is an error appeared in JS console:
Uncaught TypeError: Cannot read property 'props' of undefined(anonymous function) @ main.js?ver=4.3:92(anonymous function) @ main.js?ver=4.3:20j

Alex,

would you be able to contact us directly at [email protected] to speed this up?
