Script integration back into website. Photo Taking Browser Application

I have a website with browser scrips that no longer work after site was moved to new server (javascript, node.js, json). Site is [login to view URL] The "Take Passport Photo" button is supposed to turn on a visitors webcam...takes a photo etc. I would like this functionality integrated back into my website. No design is necessary. Though I know my site needs work:)) I have the scripts and can resend upon hire. Wordpress is already installed with a custom theme and WooCommerce. A similar site (non webcam) is: [login to view URL] Just looking for functionality back into the site with the webcam taking a photo of a person and having that photo go to the backend of wordpress. Ability to purchase the photo (WooCommerce) needs to function as well. Ability to have the customer download the photo after a e-mail input is very desirable too if possible. Ability to have a customer "Upload" a photo from their computer to the site or my backend and order services through WooCommerce is desirable too. I can give more specifics after applicants have been narrowed down. Only taking hires from North or South America, Europe or Auz/NZ. Many thanks!
