Why do I get a 429 request status when I download some pictures?
Some downloads without problems, some with 429 request status

Because you download too many images at the same time.The server has concurrency restriction.

I thought so, but I was alarmed by the fact that every time 429 error on the same pictures.
For example, I have a set of 100 pictures, 26 I download without problem, for the rest 429. And so it is every time. All the time I download without problems the same 26 pictures. Every time I run the script, it's the same pictures. I also tried running the script ONLY on those pictures where I got 429. In the end, I couldn't download any of them. Tried to take one picture and download it, all the time 429 =\
