On cdn.wallapop.com, whenever pictureSize=W<number> and number < 1024, replace with W1024, to view individual pictures of items at higher resolution than provided by default.
Tested with Tampermonkey v5.3.3.
By default Wallapop shows pictures of items at a pre-defined size (when opening the picture in a new window/tab): 640 or 800 pixels width. At least a width of 1024 is available for every tested article. This script sets that query size of 1024, or uses higher if is already in the URL.
Wallapop is a Spanish from Spain website like eBay or Vinted to buy/sell used goods.
