This plugin stops only images from uploading directly to your <a href="http://aws.amazon.com/s3/" rel="nofollow ugc">Amazon S3</a>, <a href="https://www.digitalocean.com/products/spaces/" rel="nofollow ugc">DigitalOcean Spaces</a> or <a href="https://cloud.google.com/storage/" rel="nofollow ugc">Google Cloud Storage</a> by filtering <a href="https://deliciousbrains.com/wp-offload-media/" rel="nofollow ugc">WP Offload Media</a>. All other media file types continue to upload.
This is great for those who are wanting better SEO Image search results as the images will be loading from your site and not from your CDN of choice.

Block Uploading Images for WP Offload Media

Stops images from uploading directly to your choice of CDN storage service.

DigitalOcean Spaces Sync plugin connects your Media Library to a container in DigitalOcean Spaces. It syncs data from your website to cloud storage 
and replaces links to images (optional). You may keep the media locally (on your server) and make backup copy to cloud storage, or just serve it all 
from DigitalOcean Spaces.
In order to use this plugin, you have to create a DigitalOcean Spaces API key.
You may now define constants in order to configure the plugin. If the constant is defined, it overwrites the value from settings page. 
Contants description: 
– DOS_KEY – DigitalOcean Spaces key 
– DOS_SECRET – DigitalOcean Spaces secret, 
– DOS_ENDPOINT – DigitalOcean Spaces endpoint, 
– DOS_CONTAINER – DigitalOcean Spaces container, 
– DOS_STORAGE_PATH – The path to the file in the storage, will appear as a prefix, 
– DOS_STORAGE_FILE_ONLY – Keep files only in DigitalOcean Spaces or not, values (true|false), 
– DOS_STORAGE_FILE_DELETE – Remove files in DigitalOcean Spaces on delete or not, values (true|false), 
– DOS_FILTER – A Regex filter, 
– UPLOAD_URL_PATH – A full url to the files, WP Constant, 
– UPLOAD_PATH – A path to the local files, WP Constant
There is a known issue with the built in WordPress Image Editor, it will not upload changed images. Know how to fix this, PR welcome.

DigitalOcean Spaces Sync

If it was possible to give a less than 1 rating I would happily do it. This plugin did not sync my media with DO spaces. What's worse, all media links on my website now link to my DO spaces CDN even though they were not synced. As a result, all images on my website appear broken.

I wrote to support and received no reply so I'm left with nothing else to do but restore a backup of my site. I'm more than disappointed.

Don't use this on a production website

This WordPress plugin syncs your media library with DigitalOcean Spaces Container.
