Hello,
I tried to get the Images of the thumbnails on the left.

click on a thumbnail, get the large image
click on next thumbnail, get the large image
...

I already tried several types of selectors without success.
May you can point me to the right direction?

Thank you!

@Klaus.Meier Hi, have you tried using the 'Grouped' selector - .gallery-img-wrap img with an attribute name - src? Due to the slow rendering speed of this website the scraping job should be launched with the page load delay value set to at least 3'000-4'000 ms, otherwise the rest of the images might be missing from the final data. Alternatively, you can resize the images by adjusting the part highlighted in the screenshot(from 755x1000 to 1200x1000).

Example:

{"_id":"butyomet_shoe","startUrl":["https://www.butyotmet.pl/trzewiki-meskie-002do-b60.html"],"selectors":[{"extractAttribute":"src","id":"all-images","parentSelectors":["_root"],"selector":".gallery-img-wrap img","type":"SelectorGroup"}]}

SOOOO great, thank you!
