For example, download the attached links and save these pictures to the C: directory.

Thanks!

Here is a very simple script that I believe will do what you want

Names Default To Here( 1 );

// Create a list of all of the images
imgList = {"http://data2.readoor.cn/files/3211195850f6ae/pdf/9213745e4f7c7b/3/859de8ee2b9187a0e73d764fd53466e4.jpg",
"http://data2.readoor.cn/files/3211195850f6ae/pdf/9213745e4f7c7b/3/.........",
"http://data2.readoor.cn/files/3211195850f6ae/pdf/9213745e4f7c7b/3/........."};

// Read in and write each of the images
For( i = 1, i <= N Items( imgList ), i++,
	img = Open( imgList[i], jpg );
	img << Save Image( "C:\image" || Char( i ) || ".jpg", jpg );
);

The Open() and Save Image() functions are Documented with examples in the Scripting Index.

Thank Jim!
I used to write it this way, but it didn't work.

request = New HTTP Request(	Url("http://data2.readoor.cn/files/3211195850f6ae/pdf/2977675e4e6cb5/3/f0df50279eeaa6465bfaf4e93525e81a.jpg",jpg),
	Method( "GET" ),
);
img  = request << Send;
img << SaveImage( "C:/1.jpg", jpg );

dt=Current Data Table();
imgList = Column( "url" ) << get values;
For( i = 1, i <= N Row(dt), i++,
	img = Open( imgList[i], jpg );
	img << Save Image( "C:\image" || Char( i ) || ".jpg", jpg );
);
