How can we implement the feature of changing images in …

To implement the image replacement feature, you can use the PictureBox control to display the image and use the OpenFileDialog control to select the image you want to replace. Here is a simple example:

1. Add a PictureBox control and a Button control to the form.
2. Double-click on the Button control to enter its Click event handler.
3. In the Click event handler, use the OpenFileDialog control to select the image to be replaced and assign its path to the ImageLocation property of the PictureBox control.

The sample code is as follows:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim openFileDialog1 As New OpenFileDialog()
    
    ' 设置可以选择的文件类型
    openFileDialog1.Filter = "图片文件|*.jpg;*.jpeg;*.png;*.bmp"
    
    ' 如果选择了文件并点击了“确定”按钮
    If openFileDialog1.ShowDialog() = DialogResult.OK Then
        ' 将选择的图片路径赋给PictureBox控件的ImageLocation属性
        PictureBox1.ImageLocation = openFileDialog1.FileName
    End If
End Sub

When the Button control is clicked, a file selection dialog box will appear, allowing you to choose an image to display in the PictureBox control.
