@freddy this I didn’t know, but very happy cryptee are on to it and implementing a solution:

“Since remote images make connections to remote servers every time you open a document, the remote images' servers (and their owners) can track:
when & how often you open a document with the pasted image,
the location where you open a document using your ip address
the device with which you open a document (phone/laptop etc)

We think that's absurd, unacceptable and a gross violation of your privacy.
Starting with this version, when you copy paste anything into Cryptee, or when you import 3rd party files like html, markdown, or evernote notes into Cryptee, Cryptee will scan for remote images, block them from loading, and ask if you'd like to load them.”
