Images not shwoing up in Safari

There's a few reasons why this could be happening. But alot of the time it's because of an extension or ad blocker that is installed.

Try this: Hovering over your reload button in the Smart Search address bar, left-click and hold the mouse button down. A context menu will pop up, --select Reload Without Content Blockers, and release the mouse button.

That will reload the page and temporarily disable any blocker that's giving you trouble. And it's quicker than trying to remove the extension you installed in the first place.

Here is a couple of support articles with more information:
