如何使用python dash使用循环显示多个图像

import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output

app = dash.Dash(__name__)

app.layout = html.Div([
    html.H1('多图像显示'),
    dcc.Dropdown(
        id='image-dropdown',
        options=[
            {'label': '图像1', 'value': 'image1.jpg'},
            {'label': '图像2', 'value': 'image2.jpg'},
            {'label': '图像3', 'value': 'image3.jpg'}
        ],
        value='image1.jpg'
    ),
    html.Img(id='image')
])

@app.callback(
    Output('image', 'src'),
    [Input('image-dropdown', 'value')]
)
def update_image_src(value):
    return value

if __name__ == '__main__':
    app.run_server(debug=True)
