Yes, only the 1st photo is scanned.
From the second one onwards, you can indeed use low-quality photos or even AI-generated ones.
You need to check the image properties to see this metadata.
Either with your Windows, or with Exiftools (for example)
I read on social media that taking the first photo with Vinted’s built-in camera helps a lot with visibility. I don’t use AI. Just my iPhone. Before, I used a real camera, but given what Vinted does with our photos and the terrible rendering, the iPhone is enough 
. So, I’m experimenting with the Vinted camera… and 
Pathetic. No cropping or settings possible. And of course, it steals the photo that doesn’t go into your library. Hey… doesn’t that sound familiar and bring up conversations about photo ownership? Could this be it? Anyway, I’ll keep taking photos on my iPhone.
you mean he has the photos in his library and therefore there is a copy?
When you go to the ‹ publish an ad › function, adding photos, there is a camera before the +. If you click on it, it takes the photos and sends them directly to the ad. Like on Instagram (except on Insta you keep the photo) So you took a photo but it doesn’t belong to you. You don’t even have it in your library
