Hi,
  
public class ImageUri {
    public static String getDataUriFromUri(String url) {
        HttpRequest req = new HttpRequest();
        req.setEndpoint(url);
        req.setMethod('GET');
        Http binding = new Http();
        HttpResponse res = binding.send(req);
        Blob image = res.getBodyAsBlob();
        return 'data:'+res.getHeader('Content-Type')+';base64,'+EncodingUtil.base64Encode(image);
    }
}


Attachment n = new Attachment();
//You will want to tie your attachment to some type of custom or standard object
//n.ParentId = myAccount.Id;
n.Name ='myImage.jpg';
n.Body = image;
//If we were saving a PDF as an attachment the ContentType would be'pdf'
n.contentType ='image/jpeg';
insert n;

Thanks
Jai
