    String base64Data = '';
    HttpRequest req = new HttpRequest();
    req.setEndpoint(image1);
    req.setMethod('GET');
    Http http = new Http();
    HttpResponse res = http.send(req);
    Blob image = res.getBodyAsBlob();
    base64Data =  EncodingUtil.base64Encode(image);
    System.debug('image= ' + image);

    Document docatt = new Document();
    docatt.Name = 'Chart 1.jpg';
    docatt.Body = EncodingUtil.base64Decode(base64Data);
    docatt.FOLDERID = '00l6F231005tqGi';
    docatt.IsPublic = true;

    insert docatt;

}

Image file that was saved:

Assuming the image1 URL you have works fine from a browser session then the problem will be a missing cookie with a Salesforce Session ID to authenticate the request. You will need to set the sid cookie to a valid Session ID. — Daniel Ballinger, Apr 20 '17 at 02:34

You will need to set a valid sid cookie on the request to authenticate it.

HttpRequest req = new HttpRequest();
//...
req.setHeader('Cookie', 'sid=' + UserInfo.getSessionId()+ ';');
//...

Also consider the HttpResponse to see what went wrong. E.g.

HttpResponse res = http.send(req);
System.debug('Status Code: ' + res.getStatusCode());

just wondering if there way? It's because I want to put his into a scheduler to insert the image into the Document Folder and I might not be online at that point of time that it upload the image file – Luke Au Apr 20 '17 at 03:03
Establishing a session from a scheduled job is a whole other problem. Have a search, as there are other questions that have addressed that issue. – Daniel Ballinger Apr 20 '17 at 03:27
Session ID from scheduled jobs – Daniel Ballinger Apr 20 '17 at 03:30
The last time I tried putting 2 HTTP method in the same class I had an error. The other method that was given I don't understand the codes to implement it into the scheduler. – Luke Au Apr 20 '17 at 04:13
