This paper investigates the issue where external PNG image resources referenced by <image> tags within SVG files fail to display in Chrome when the SVG is embedded in an HTML page via the <img> tag. The core cause is browser-imposed resource isolation for security and privacy, restricting access to third-party files. Based on the best answer, the article details the solution of using the <embed> tag instead of <img>, which bypasses these restrictions and allows normal loading of external images. As supplements, alternative methods such as converting PNGs to Data URI format or SVG path elements are discussed, with complete code examples and implementation steps provided. By comparing the mechanisms of different embedding approaches, this paper deeply analyzes the impact of browser security policies on SVG rendering, offering practical technical guidance for developers.
