CSP: img-src

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since August 2016.

The HTTP Content-Security-Policy: img-src 지시어는 이미지 및 파비콘에 대하여 유효한 출처를 지정합니다.

CSP version 1
Directive type Fetch directive
default-src fallback Yes. If this directive is absent, the user agent will look for the default-src directive.

Syntax

img-src 정책에 대해 하나 이상의 출처를 허용 할 수 있습니다.

Content-Security-Policy: img-src <source>;
Content-Security-Policy: img-src <source> <source>;

Sources

<source> can be any one of the values listed in CSP Source Values.

Note that this same set of values can be used in all fetch directives (and a number of other directives).
