功能请求：复制当前图片或另存为图片|Feature Request: Copy Image Or Save as File

[Jiang10086]

当看到精彩处想分享，截图往往会损失精度，要是能快捷复制图片或者另存为图片就好了

When you come across something interesting and want to share it, taking a screenshot often results in a loss of quality. It would be great if there was a quick way to copy the image or save it as a separate image file.
