External tool suddenly needed to view copied photos

When I copy ANY photos off the internet into a Libre Ofice doc., it suddenly says I must use the external tool to view them. This never happened before. What changed and how do I fix it? It’s driving me CRAZY1 Thank you.

You gotta give us a little more information than that (click “add a comment” or “edit” your question). OS? LO version? Maybe even which browser you’re using. Are you using drag-and-drop or copy-and-paste?

There are geniuses and experts here but (AFAIK) no mind readers.

… and what is “it” that suddenly says? I mean, is that a message from LibreOffice? or from OS? at which specific moment it appears? what happens next, e.g. when you close the message? Which is exact wording? Better a screenshot…
