// @description Launch a script on Pinterest that automatically scrolls the page and converts all images on the page into large images (with links, names) to be added to the Eagle App.
// @description:zh-CN 请确保你的网路环境可以正常访问 Pinterest，如果设备网路无法访问，此脚本将无法正常运作。在 Pinterest 画版页面启动脚本，此脚本会自动滚动页面，将页面中所有图片转换成大图（包含链接、名称），添加至 Eagle App。
// @description:zh-TW 在 Pinterest 畫版頁面啓動腳本，此腳本會自動滾動頁面，將頁面中所有圖片轉換成大圖（包含鏈接、名稱），添加至 Eagle App。
// @description:ja-JP Pinterestのボードページ上でスクリプトを起動すると、ページが自動的にスクロールし、ページ上のすべての画像を大きな画像（リンク、名前付き）に変換してEagleアプリに追加することができます。
