Hey Nithin MK AS per your code you did all things perfectly ok.

in the current situation, only the first file is uploading on the server. I think if you are not uploading the first file and uploading the second file it would be uploaded.

So I suggest that you can use the array for this. if your web service using php/.net then you can use the array for the file name.

so try with use

name=\”image2[]\”;

name=\”image3[]\”;

and also please check your web service with this.

Thanks.
