Easy to scrape site - getting images looks like a real challenge!

Hi, hope you can help....

I am trying to get the details and images from this site, but finding the codes required to upload for the URL and the cookies/headers for the api to get the images has me totally stumped

https://www.cva-auctions.co.uk/auction/25

The Images api looks like this: https://br-api.aos.tv/vehicles/MT21XRK?cb=1748345775577 - I can get the MT21 part of the URL but no idea where the las part of the query string comes from. Until I get past this I can't test the header/cookie records etc.

Any help gratefully appreciated.
Thanks
