It may be that they don't allow hotlinking. You can upload the image to a site like imgur or tinypic. There are lots of free image hosting sites to choose from.
Edit to add
This is the message I get when I right click and choose view image on the thingy that shows up in your post -
Requested URL (
https://images.app.goo.gl/WEn4X3AxpLQawjaYA.jpg) must be a parseable URI, but possibly incomplete to be a DynamicLink.
If you are the developer of this app, ensure that your Dynamic Links domain is correctly configured and that the path component of this URL is valid.
