| # safeImageUrl | |
| This is a small module that takes a URL to a supposed image and returns a safe | |
| version of it, guaranteed to be hosted by Automattic. If the URL appears to be | |
| from an Automattic-controlled CDN, it is simply upgraded to HTTPS if necessary. | |
| If it is not on an Automattic-controlled CDN, the URL is routed through photon. | |
| ## Example | |
| ```js | |
| import { safeImageUrl } from '@automattic/calypso-url'; | |
| safeImageUrl( '//example.com/foo.png' ); | |
| // "https://i1.wp.com/example.com/foo.png" | |
| ``` | |
