Solution 1

Try:

C#

protected void imgbtnSlideShowPic_Click(object sender, EventArgs e)
{
    ImageButton ib = (ImageButton)sender;
    string objSenderID = ib.ID;
    // you know the ID of the image button clicked!
    // Use the way you like!
}

I would recommend you to set ID while generating the ImageButton. Try this:

C#

int count = 0;
foreach (string strDirectories in strImageAdress)
{
    if (strDirectories.Contains('.'))
    {
        count ++; //Increase you count by one
        imgbtnSlideShowPic = new ImageButton();
        imgbtnSlideShowPic.AlternateText = @"..\Images\ImagesHome\" + strDirectories;
        imgbtnSlideShowPic.ID = "imgbtn"+count.ToString();
        //Here we have given ID to the button.
        imgbtnSlideShowPic.Height = 50;
        imgbtnSlideShowPic.Width = 50;
        imgbtnSlideShowPic.ImageUrl = @"..\Images\ImagesHome\" + strDirectories;
        pnlSlideShowController.Controls.Add(imgbtnSlideShowPic);

    imgbtnSlideShowPic.Click += new  ImageClickEventHandler(imgbtnSlideShowPic_Click);                     
    }
}
protected void imgbtnSlideShowPic_Click(object sender, EventArgs e)
{
    ImageButton img = (ImageButton)sender;
    string btn = img.ID;
    //write your code here
}
