Is there a way to add pics to a message/comment/thread? I don't see a link. Thanks!

Grab the link/URL to the image, e.g. "https ://www.gardeningknowhow.com/wp-content/uploads/2015/04/sequoia-strawberry.jpg"

Be sure it ends in an actual image file format e.g. .jpg, .png or .gif

Paste the link to the image file in the comment and it will embed the image.
