While editing a note just now, I had to use the HTML <center> tag to center-align an uploaded image, and had to remove the markdown code starting with an exclamation mark and instead use the <img> HTML tag to embed the image.
This got me wondering about how supernotes manages images. I was concerned that by (deleting the markdown part and) using just the auto-generated URL and embedding the image myself with the <img> tag, supernotes might recognize the image I just uploaded as an “unused image”. If that were the case, I would be worried that the image I attached might be removed soon in accordance with the general principle of removing unnecessary images that were previously attached but are no longer used in notes, in order to efficiently operate the server.
In conclusion, is it safe to use only the URL from auto-generated image attachment markdown code? (Will I be able to see the same image even after several years?)
