added a simple python script for converting JPG image into PNG

[LAbhilashKumar]

This PR is on the JPG to PNG conversion task as assigned. This script leverages the Python Imaging Library (PIL) to open a .jpeg image and save it as a .png format.

Addresses issue: #204

Thank you for your contribution and for submitting the JPG to PNG conversion script!

A couple of notes based on our repo’s contribution guidelines and best practices:

1. Refer to CONTRIBUTING.md and README.md
   Please ensure your pull request description follows the structure outlined in our CONTRIBUTIONS.md file. Also, don’t forget to properly update the main README.md by adding your script to the List of Scripts section with a brief description and a link to your folder. This helps maintain consistency and clarity for all contributors.

2. Add a README.md for your script folder
   Each script folder should include a README.md that explains what the script does, any dependencies it has, and how to run it. This makes it easier for users to understand and use your script.

3. Avoid Hardcoded File Paths
   Currently, your script uses a hardcoded absolute path to open the image (r"C:\Users\ABHILASH\OneDrive\Desktop\iron man_jpg.jpeg"), which won’t work on other machines or operating systems.
   To make the script more portable and user-friendly, consider:

• Accepting the input file path as a command-line argument or
• Placing the image file in the same folder as the script and referring to it with a relative path.

4. Suggested code improvement
   For example, you could modify the script to accept an image path from the user like this:

import sys
from PIL import Image

if len(sys.argv) != 2:
    print("Usage: python convert.py <image_path>")
    sys.exit(1)

input_path = sys.argv[1]

try:
    image = Image.open(input_path)
    output_path = input_path.rsplit('.', 1)[0] + '.png'
    image.save(output_path)
    print(f"Image saved as {output_path}")
except Exception as e:
    print(f"Error occurred: {e}")
