Pinboard Joomla 3 component customization

This project is for custom modifications to the Joomla 3 extension TZ Pinboard by Templaza ( information and demo at [login to view URL] ). The Pinboard extension is a free download on GitHub. On the Templaza website, you can access it by going to Joomla Extensions > TZ Pinboard. We have already purchased the Pinme template.

 Background explanation: • Our main e-commerce website uses Netsuite ERP • We will be adding the Pinboard extension on a separate Joomla install in a subdirectory, i.e. [login to view URL] • The Joomla / Pinboard installation will be our social media portal where customers can pin their own photos of how they use our products and share with their friends. • When a new pin is added by a customer it is unpublished until approved by a site administator. When reviewed, the administrator will identify the matching product, add photos of up to 6 related products with the URL link to each product's details page on the Netsuite site. When published, visitors to the Pinboard will see the customer's original pin with a new "Shop This Look" section that includes the product images and links. This is the part we need added to the Pinboard extension. Modifications desired: Change layout on lightbox view when you click a pin. We would like it similar to [login to view URL] - and see the attached screenshots. 

1. Title at top left
 2. Smaller main pin image so it's not full width.
 3. "Shop This Look" section to the right of main image. 
This includes "Shop This Look" title text with shopping cart icon, small photos of up to 6 products (2 per row, 3 rows), each photo linked to that product's detail page on the Netsuite site. Rollover effect on each product image thumbnail similar to [login to view URL] but using a shopping cart icon rather than the zoom/magnifying glass image they use.
 4. Everything below the main photo can remain the same as the original Pinboard design. 

I believe these layout changes could be added to the template overrides at templates > tz_pinme > html > com_tz_pinboard > detail > [login to view URL] so any future updates to the extension won't break our modifications. 

The new "Shop This Look" section requires some additional fields added to the Pinboard admin backend at Components > TZ Pinboard > Pins:
 1. Field to select or upload the related product images - up to 6 for each pin. 
2. Field to enter URL link for each product photo - enter absolute path, not relative.
