Yahoo Mail blocking images, pictures in email preview

If you are receiving emails to your Yahoo Mail account and the software is blocking images, here's how to fix it.

Here's what an email looks like in Yahoo Mail with images blocked. You will see a message at the top of the screen saying "This message contains blocked images. Show Images."

To unblock all images (except images in your spam folder), go to:

Cog icon > Settings > Security >

and ensure that next to "Show Images in emails", you have selected the option "Always, except in Spam folder".

Now when looking at the same email as above, the images show in the email preview where they should be!
