When you post, message, or write an article with a URL, the preview window may show an old image that is cached. This means that if you have shared the same URL before, the image might already have been stored in the cache and that's what you see when you try to add it to your new post, message, or article. You can use the Post Inspector as a tool to refresh the URL.

To use the post inspector tool to refresh URL:

1. Click Post Inspector.
2. Enter the URL you want to share.
3. Confirm that the preview window shows the correct content.

Note: The changes you make will only affect the URL's preview image and information for new posts that include it. The preview for any existing posts with this URL will remain the same.
