[ATEC_dev]

HI 

am new with Prestashop and PHP, i need to create a module that upload some videos related to products. So i search in Google and i find a project (Ajax, JQuery) that make the whole work (uploading selected files), and there is many JS, CSS and PHP files but i don't know how to integrate them into my project !

i already prepare the  module and  relate it to the product page.

maybe i deedn't express my needs well but any ideas or suggestion well be grateful and sorry for my bed English.
