import { useState } from 'react'
import './Img.css'
import { MdClose } from 'react-icons/md';interface ImgProps {src: string;alt: string;size?: 'small' | 'medium' | 'large';onClose?: () => void;
}const Img = ({ src, alt, size = 'small', onClose }: ImgProps) => {const [showPreview, setShowPreview] = useState(false);const [visible, setVisible] = useState(true);const handleClose = () => {setVisible(false);if (onClose) {onClose();}};if (!visible) return null;return (<div className={`img-container img-${size}`}><button className={`img-close img-close-${size}`} onClick={handleClose}><MdClose /></button><div className={`img img-${size}`} onClick={() => setShowPreview(true)}><img src={src} alt={alt} /></div>{showPreview && (<div className="img-preview-overlay" onClick={() => setShowPreview(false)}><div className="img-preview-content"><img src={src} alt={alt} /></div></div>)}</div>)
