  just for urgent needed, dont spam this.
  Just copy this script into web console and run the function. 
  If you want to download the image, just edit downloadFile=true
  
  Note: 
  - workflow: get all image src or div background-image, then filter it as our needs
  - you can edit this file to scrape another website if you want. just change my regex or remove it

  Usage:
  1 open google maps url like : https://www.google.com/maps/place/Mloko+Sewu/@-7.79157,111.6462699,3a,75y,90t/data=!3m8!1e2!3m6!1sAF1QipMtMGxW_muPjPM5RZQhCoOWlnlUdxv_tyfoC3w!2e10!3e12!6shttps:%2F%2Flh5.googleusercontent.com%2Fp%2FAF1QipMtMGxW_muPjPM5RZQhCoOWlnlUdxv_tyfoC3w%3Dw203-h121-k-no!7i4000!8i2403!4m5!3m4!1s0x2e79a5eb33449f27:0xfdee7e62b1634c5!8m2!3d-7.79157!4d111.6462699
