Rename Files before downloading with JSZip Downloader App

Job ID: 33013554

Budget: $10 – $30 USD

We want to extend the functionality of this JS Downloader example here - https://stuk.github.io/jszip/documentation/examples/downloader.html.
The application allows users to select a list of files, zip, and download them. But we want to be able to rename the files before they are downloaded. For example, if the files to be downloaded are cat.jpg, dog.jpg, lion.jpg;, we want to rename them into sitename-cat.jpg, sitename-dog.jpg, sitename-lion.jpg, etc or just sitename-img01.jpg, sitename-img02jpg, sitename-img03.jpg
