Assume that I have 20 images with sequence number like "happy_1.jpg" to "happy_20.jpg" then I need to upload all 20 images to server. However I don't like to click 20 times to enter the images into File field. Is there anyway that I can generate them in javascript and fill into the each File fields? If this is not possible then can it be done from server side? I have research for whole day but no luck. Thank you.
