Try using DevTools to figure out what’s going wrong.
Press F12 (or right-click and choose Inspect) and check the Console for red error messages — for example, a 404 means the image wasn’t found, usually because the path or filename is wrong.
Next, go to the Network tab and reload the page. Filter by Img and look for errors like 404 (file not found) or 403 (access denied).
You can also right-click the <img> in the Elements tab and choose "Open in new tab". If the image doesn’t load there, the file path or name is likely incorrect.
