There's quite a few flexible options to install your Gallery once you've completed the setup and you have some Gallery Items ready to display.
This is a page that sits on the Gleam.io domain and will show the Gallery at all times. We also use this landing page with Share links so we can show the user their Share to vote on.
When choosing to embed on your site, you can set a few options first. For example you can choose to completely remove the header and just embed the images if you wish.
Once you've selected your options you'll see two piece of code to embed. The first piece of code should code in your header or template.
The second piece of code embeds the Gallery on your page. So just put that where you'd like the Gallery to show. Our Gallery is responsive, so it'll scale to fit within the size of the holding page.
The final option allows you to embed your Gallery inside a Facebook tab. Again just choose your configuration, then click the Facebook install link.
