a.您可以尝试通过image = image.resize(X,Y)下载后调整图像大小
B.如果 a 不适合你，那么你需要了解搜索引擎上的图像搜索结果会显示图像的缩略图，而不是实际的图像。我们看到的是缩略图和原始位置是其他地方，如果你想下载他们在原始大小，那么你需要去该网站并从那里下载。

你正在提取图像的url，这是缩略图，当然不是完整的图像。不幸的是，这个网址有点难以获得，因为它不会在查看图像时加载，只有在点击它之后。
这同样很难模拟，因为据我所知，它是通过javascript加载的。你可以重写整个过程，使用一个Web驱动程序，比如Selenium来模拟用户与图像的交互，从而能够加载它们。
我将包括一个小脚本，搜索'小丑'和下载的前10个图像，它发现，在其全分辨率通过Selenium在一个无头设置和地方，他们在一个名为'图像'目录

注意：XPATH和CSS选择器是目前为我工作的，但它可能需要一些调整，这取决于页面加载是否不同。
