You can click on the image for a larger preview and then click the < / > embed icon. You’ll also see twitter and tumblr shortcuts to allow for quick sharing on those platforms.
Once you have clicked the embed icon, you’ll see a small piece of iframe code which you can then enter into the html view of your CMS’ editor.
In your Spindogs CMS, look for the icon that says “HTML” in the middle row of your text editor. Paste the code where you would like the image to appear and press “update”. (This will also apply to many other CMS’)
