And it will because you visited the site and have the image in your browser cache.
When posting a pic, after hitting "Preview" then hit the reload button at the top of your browser. You may need to confirm that you wish to resubmit, just click 'yes' and if the website you linked the image from allows hotlinking, you will still see the pic.
If they don't, you'll see a broken pic icon or the the site may replace the image with a "no hotlinking allowed" image.
Thanks! I did not know that. Been posting pictures for years and I’m sure I’ve done it in the past yet no one notified me of it.
