CustomUrl

If you prefer to use your own default image (perhaps your logo, a funny face, whatever), then you can easily do so by using the CustomUrl option and supplying the URL to an image.

Rating and size parameters are ignored when the custom default is set. There are a few conditions which must be met for default image URL:

• MUST be publicly available (e.g. cannot be on an intranet, on a local development machine, behind HTTP Auth or some other firewall etc). Default images are passed through a security scan to avoid malicious content.

• MUST be accessible via HTTP or HTTPS on the standard ports, 80 and 443, respectively.

• MUST have a recognizable image extension (jpg, jpeg, gif, png, heic)

• MUST NOT include a querystring (if it does, it will be ignored)
