Description
Applications running on PHP 8.2 can create, resize, and transform images on the server. This runtime extension is used by upload handlers, thumbnail generators, chart renderers, CAPTCHA systems, and CMS media tools. It is dependency-only and has no separate launcher; PHP code calls GD functions when enabled. Image files from users need size limits, type checks, and safe storage paths because malformed or huge images can consume resources or expose parser issues.
