How to upload an image in the announcement section?

In version there is no option to upload images in the announcement, how do I upload images?
I always get this error when I drag the image to the announcement: cannot convert blob:https://xxxxxxxxxxxxx to Blob. Resource might not exist or is inaccessible.

Please, help me!
