Uploading multiple images for one product

Hi folks,
I have downloaded a script for listing real estate property. Only the last photo to upload shows up. Can anybody look at the code and see if some wrong. Thank you all.

Thank you very much. I have tried using different names for the input element like you suggested but no image is uploaded at all. Could you please help with how the foreach would look like in this particular case.
