Similarly, a weblink can stay the same but have different redirect targets.\n\nThis way you can deliver your latest offers or messages even years after the digital assets were created. There's no need to update the whole content library - just keep the dynamic images and links fresh.\n\n## Requirements:\n- A [shorten.rest account ](https://shorten.rest/) for creating URL with dynamic redirect target URLs.\n- A [GitHub account](https://github.com/) to store the dynamic images\n\n*Both services work for free, but you can swap them with your own URL shortening / redirecting service or an S3 bucket for storing an image*"
