The easiest way to add link to your Image or Video is using PostLink app.
The app adds a small QR Code inside the Image or Video, this contains your link, and that’s it. It is placed on the corner of the post, so it wont ruin the beauty of it.
You can also use a shortener service like bit.ly and dinamically change the link, to keep it always updated.
Your users will be able to scan it, in a variety of ways, due to the pandemic, they are now aware of how to read a QR Code.
Our fast-way suggestion is: take a screenshot and share it with a QR reader app (iOS does this scan automatically without third party apps).
Give it a try, now, get PostLink here.
