@amirfarbodrm-0267，Welcome to Microsoft Q&A, you could try the following code to set a timer to mouse down for 5seconds and then show or hide the picture.

 public Form1()
         {
             InitializeComponent();
             timer1.Interval = 5000;
         }
    
         private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
         {
             timer1.Start();
          
         }
         int count = 0;
         private void timer1_Tick(object sender, EventArgs e)
         {
             if(count==0)
             {
                 DialogResult dialogResult = MessageBox.Show("Sure?", "Hide the photo?", MessageBoxButtons.YesNo);
                 if (dialogResult == DialogResult.Yes)
                 {
                     pictureBox1.Visible = false;
                 }
                 else if (dialogResult == DialogResult.No)
                 {
                     pictureBox1.Visible = true;
                 }
                 timer1.Stop();
                 count++;
             }
         }

Result:

Best Regards,
Jack

Your approach of starting your timer in the mouse down event, killing it in a mouse up event, and when the timer expires, do what you need, should work.
So what aspect of it didn't work?
