In practice, many clients and servers do only support URLs up to a certain length.If you pass image as param along with the URL,sometimes, URL's length maybe to too long.

I suggest using HTTP/POST to upload multipart files.There is some sample code using ASIFormDataRequest to upload multipart files:

NSData * imageData1 = UIImageJPEGRepresentation([UIImage imageNamed:@"image1.png"] ,0.6);
NSData * imageData2 = UIImageJPEGRepresentation([UIImage imageNamed:@"image3.png"] ,0.6);
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request addData:imageData1 withFileName:@"image1.jpg" andContentType:@"image/jpg" forKey:@"certImage"];
[request addData:imageData2 withFileName:@"image2.jpg" andContentType:@"image/jpg" forKey:@"certImage"];
[request startAsynchronous];
