WooCommerce Gallery & Checkout Fix

My WooCommerce site is already online, but three things still need a specialist’s touch:

• Masonry-style catalogue view
I want a plugin (or custom code) that lets me pick a parent category and instantly show every product from its sub-categories in one Masonry grid. Filters must stay fast and fully responsive.

• Weight-based shipping + country logic
Set up rates that read the cart’s total weight, allow my own pickup-point option, and automatically open shipping to additional countries outside Cyprus. The back-end settings have to remain easy for me to update later.

• Country-aware payments
Credit/Debit Card should show for everyone, while Pay on delivery must appear only to shoppers in Cyprus or choosing a local pickup point.

• Product page gallery fix
Right now each image loads full-size instead of one main image with thumbnails. It’s a CSS/JavaScript conflict that needs to be traced and resolved so the standard slider/lightbox works again.

Acceptance criteria
– New Masonry gallery loads in <2 s with lazy-loading images
– Shipping rules calculate correct fees across at least three test weights and two external countries
– Payment methods display exactly as described, verified through checkout sandbox orders
– Product page gallery view behaves like WooCommerce default on desktop and mobile, no console errors

The site runs WordPress + WooCommerce on the latest stable versions; you’re free to use well-maintained plugins or lightweight custom code as long as updates remain hassle-free.
