Social media cards

Short description of functionality and look and feel:
Images + short copy (think of a tweet) + a custom url (call to action) that can be shared on social media with one (or two clicks). In addition, there will be a download link, in case people want to share the card on Instagram or another platform that does not allow this one click functionality.

You can see similar functionality on the NG website. Scroll down to Challenge Your Friends section.

Keep in mind that this is just an example. When the "Share on Twitter" button is selected, the image should appear as part of the tweet. In the NG example, this is not possible but Twitter allows this functionality. It is called Twitter cards. Ideally we should be able to customise the url (call to action) so that we can send people to any page we want. Not sure if this is possible for Facebook because we can put only one url in the meta code. It looks like the NG people managed to do.

Check if possible but if not, we can just have "share on twitter" and "download image" functionality.

In terms of design, I am happy with a scroller of even the grid image gallery P4 layout as long as the style/colours are aligned with the plastics theme. The copy that you see on the image in the NG example is part of the image. No need to add it as an overlay.
