## Overview

Image Preparing Lab is a small Streamlit image-preparation prototype. The user uploads an image, reviews its dimensions and megapixels, validates crop coordinates, and crops it. The app measures the crop and, when it is below the 5 MP target, resizes it, encodes a quality-95 JPEG, and offers it for download. The graph follows the sampled app and processor code; no persistent storage or separate external processing service is shown.

Main entry points: [`app.py`](https://github.com/syedanazish-debug/image-preparing-lab/blob/main/app.py) (Upload and workflow), [`image_processor.py`](https://github.com/syedanazish-debug/image-preparing-lab/blob/main/image_processor.py) (Target resizing)
