Embedding Tumblr Posts:
Tumblr offers embed codes to place a published post on any website that allows an HTML embed. From the Desktop Dashboard, simply click the three-dots icon and select "Embed" from the sharing menu. But what if that post isn't on your Dashboard right now? Try these tips.
Feb. 20, 2015 Update:
Tumblr added an Embed button to individual blog post pages.
If you have the post URL to its individual page — also known as a permalink — add /embed to the end of the URL, like this:
http://unwrapping.tumblr.com/post/101895859192/embed
Some blog themes end the URL with #notes — that's an anchor to jump to the notes. Remove #notes then add /embed to the end of the URL. Many thanks to strle for this tip.
If you haven't liked the post, now's the time. Like the post. Then go to https://www.tumblr.com/likes/ to see the post on your Desktop Dashboard. Click the three-dots icon and select "Embed." Hat tips to andrewwilkes and jeffreyweston.
Or try these steps to change your Desktop Dashboard URL to reveal the post. It's a bit longer process, involving some Dashboard time travel.
