Selenium 请问，data:image/png;base64 这两种编码图片如何取真实地址

滑块

图中 1 号是 “可能是背影图” 的代码
图中 2 号是 “背景图 ” 的代码
图中 3 号是 “背景图 子无素” 的代码文章源自玩技e族-https://www.playezu.com/179535.html

我想取图片，但发现图片地址被隐藏了。
如果看 id，应该是 2 号 ，但为什么 3 号跟它的内容一样呢？？？
1 号感觉也像。它和 2 号元素的 区域范围是一样大小的。文章源自玩技e族-https://www.playezu.com/179535.html

那个滑块的代码没截图。
它本来是一个滑块。可以定位并控制鼠标自动滑动。但不知道为什么 跟 “背景” 的元素写的一个风格。如果 find_elment 定位到它。可以滑动吗？文章源自玩技e族-https://www.playezu.com/179535.html
