Use `skipFirst` para excluí-la do lazy loading:\n\n```ts\nimport { compile, imgLazyLoading } from \"@unifast/node\";\n\nconst md = `\n![Hero banner](hero.jpg)\n\nSome introductory content...\n\n![Diagram](diagram.jpg)\n\nMore content...\n\n![Screenshot](screenshot.jpg)\n`;\n\nconst result = compile(md, {\n  plugins: [\n    imgLazyLoading({\n      skipFirst: 1,\n    }),\n  ],\n});\n\n// First image loads eagerly (no loading attribute):\n// <img src=\"hero.jpg\" alt=\"Hero banner\">\n//\n// Remaining images are lazy loaded:\n// <img src=\"diagram.jpg\" alt=\"Diagram\" loading=\"lazy\" decoding=\"async\">\n// <img src=\"screenshot.jpg\" alt=\"Screenshot\" loading=\"lazy\" decoding=\"async\">\n```\n\n### Pular múltiplas imagens above-the-fold\n\n```ts\nimport { compile, imgLazyLoading } from \"@unifast/node\";\n\nconst result = compile(md, {\n  plugins: [\n    imgLazyLoading({\n      skipFirst: 3, // skip the first 3 images\n    }),\n  ],\n});\n```",
