# Script Name: jpg-to-png.sh
#
# Description:
#   Recursively scans the current directory for JPG and JPEG images,
#   converts each image to PNG format using ImageMagick, and removes
#   the original JPG/JPEG file after a successful conversion.
#
#   The script preserves the original directory structure and creates
#   PNG files alongside the source images.
#
# Requirements:
#   - Bash
#   - ImageMagick (convert)
#
# Usage:
#   Convert all JPG/JPEG files under the current directory:
#
#       ./jpg-to-png.sh
#
# Example:
#   Before:
#       photo.jpg
#       images/picture.jpeg
#
#   After:
#       photo.png
#       images/picture.png
#
# Notes:
#   - Original JPG/JPEG files are deleted after conversion.
#   - Existing PNG files with the same name may be overwritten.
#   - The script processes files recursively.
