Example code from GPT 4o-mini to support capturing images from a user of a fixed size.

• File Upload: The user uploads an image, which is read using a FileReader.
• SmartCrop: Once the image is loaded, SmartCrop analyzes it and provides a suggested cropping area based on the preset final dimensions.
• Cropper.js: The suggested crop area is set in Cropper.js, allowing the user to see the recommended crop and make adjustments. The aspect ratio is fixed to the desired dimensions.
• Cropping: When the user clicks the "Crop" button, the cropped image is drawn onto a canvas with the specified final dimensions.
