请求协助从指定网站嵌入式查看器提取高清原图

Hey there! Let’s work through this together—since you don’t have coding experience but can follow step-by-step instructions, here are a few straightforward ways to grab those high-quality blob images from the frame, skipping the annoying overlay that ruins screenshot quality:

This is the easiest option if you don’t want to mess with code or developer tool details.

• Open Chrome’s built-in extension store, search for Blob Downloader or Download All Images (both are trusted tools for this kind of task)
• Install the extension, then go back to the Galeries Lafayette page
• Switch to the frame where you found the blob images (using the Frames panel in Chrome DevTools, like you did before)
• Click the extension’s icon in your Chrome toolbar, then select the option to download blobs/images. The extension will automatically detect the original, high-res images and download them without the overlay.

If you prefer not to add extensions, you can do this directly in Chrome’s developer tools:

1. Open the target page, press F12 or right-click anywhere and select Inspect to open DevTools
2. At the top of DevTools, go to the Frames panel and switch to the frame that contains the blob images
3. Switch to the Sources tab in DevTools. On the left sidebar, expand Page > select the correct frame > expand Images. You’ll see all the blob image links here
4. Right-click the blob link you want to save, choose Open in new tab
5. In the new tab, the full-quality image will load without the overlay. Right-click it and select Save image as... to save it to your computer.

If the above methods don’t work, this code will auto-download all blob images in the frame—you don’t need to understand it, just follow the steps:

1. Open DevTools (F12 or right-click > Inspect), make sure you’re in the correct frame (check the dropdown at the top of the Console tab to select the right frame)
2. Go to the Console tab, paste this code, and press Enter:

// Auto-download all blob images in the current frame
document.querySelectorAll('img[src^="blob:"]').forEach((img, i) => {
  const link = document.createElement('a');
  link.href = img.src;
  link.download = `galeries-image-${i + 1}.jpg`;
  link.click();
});

3. Your browser will start downloading all the blob images as high-res files, named galeries-image-1.jpg, galeries-image-2.jpg, etc.

小提示： #

• 一定要确保切换到了正确的frame，不然工具或代码找不到目标图片
• 等页面上所有图片完全加载完成后再尝试操作
• 如果网站临时阻止下载，刷新页面后稍等几秒再重试
