================================================================
                     PNG Compressor & Image Copier
================================================================

This script will:
  - Ask you for a folder path containing images
  - Create an 'output' subfolder inside that folder
  - Leave all your original images untouched
  - For PNG files:
       * If the PNG has transparency (alpha) -> copy original PNG to output
       * Else convert PNG to JPG
       * If the resulting JPG is LARGER than the original PNG,
         delete the JPG and copy the original PNG instead
  - For JPG, JPEG, GIF, WEBP files:
       * Copy them unchanged to the output folder
       * (If a JPG shares a name with a PNG, the JPG is skipped
         because the PNG will produce a JPG or copy itself)

Purpose: Safely compress PNGs that are better as JPGs, while
         preserving transparent images and never increasing file size.
