What is the reason why not all images are downloaded using .click ()?

Question

There is a script

let imgLink = document.querySelectorAll('.ssilkaimg');

for(let i = 0; i < imgLink.length; i++) {
  imgLink[i].click();
}

When I run the script, not all images are downloaded. 5 images can be downloaded, 10 can be downloaded, etc. But, mostly up to 15, but not all. Maybe there are some restrictions on downloading in the browser? Google did not find it.

Ruslan, in your example I can't any logic that might wait or verify images loaded status — Alex Shtromberg, Jan 03 '22 at 13:31
This may only be a temporary solution but you could use a delay. — Simone Rossaini, Jan 03 '22 at 13:31
@SimoneRossaini Yes, thanks, the postponement of the set timeout helped me. The images, as I understood, not all had time to download and the script tried to download them. — Руслан Лысенко, Jan 03 '22 at 13:37
The for loop is synchronous, you may want to return this as a promise and loop differently. — BGPHiJACK, Jan 03 '22 at 13:38
@BGPHiJACK Yes, I figured it out after asking the question)) Thanks) — Руслан Лысенко, Jan 03 '22 at 13:41

@SimoneRossaini I can leave my answer, I will choose it as correct. — Руслан Лысенко, Jan 03 '22 at 13:42

In this case the problem is the loading of the images, being that the script starts directly without waiting for the loading to finish the images will not be downloaded all, using a delay bypass the problem. (setTimeout()).
However, I recommend adopting a more correct method by waiting for the page to load an example here
