Here's my take:No that's fine. Criticise away by all means! However, post #1 in the linked thread doesn't specify what should be photographed?
So... what should be photographed? Ah... it's all in post #2!!
Preloved only allows 3 photos.
Does it help to publish emails (there are loads pre-purchase) from Chanel NBS, such as...
1. No, letters from Chanel wouldn't be helpful because as with receipts, paperwork, props, etc., they can be faked or they can be in reference to a different item.
2. If Preloved only allows 3 photos and if they don't let you put in a link to an outside photohosting site (Photobucket or the like), then find another site to sell on. To sell on a site that doesn't give you the ability to show enough information to prove authenticity is (IMO), inviting trouble.
3. Find another site to sell on where they allow up to 12 (or more) pictures.
4. Posting your pictures here seems to imply promoting them and isn't allowed. (I'd only commented and offered advice because you'd originally posted the link to the listing (also not allowed) and I saw the pictures, or rather, lack thereof.
