Weidian photos are taken by the seller, and they are usually the best-looking version of the product. QC Finder shows something else: photos taken in the agent's warehouse of actual pieces from the same listing, so you can see what the goods really look like.

The key part is the itemID parameter. Short links from the app (like k.weidian.com) work too, because the tool expands them on its own.
Listing photos are marketing material: good lighting, edited colour, sometimes a photo of the original instead of the replica. QC is a quick photo taken in the warehouse under artificial light, of the piece that is about to ship to the buyer. That is why QC looks worse but tells the truth, while the listing looks better than it should.
Because sellers resell goods from the same factories. That is where the idea of a batch comes from: one model can come from several production lines that differ in quality and price. QC is the fastest way to check which version you are dealing with before you pay.
Yes. Short addresses are expanded automatically, just paste them.
No. The QC photos come from the agent's warehouse, not from your Weidian account.
No. These are photos of pieces from earlier orders of the same listing. They show what to expect, not your specific pair.
Usually yes, as long as the goods themselves have not changed. If QC photos start to differ a lot from each other, it is a sign that the seller is mixing batches.
