  • Hello Thomas.G,

    Based on my understanding, you want to list all the image files and load them into ListBox, when select an item in the listbox, the PictureBox will display the image. If my understanding is correct, the following sample can implement this function.
    public partial class Form1 : Form
            public Form1()
                listBox1.SelectedIndexChanged += new EventHandler(listBox1_SelectedIndexChanged);

            void listBox1_SelectedIndexChanged(object sender, EventArgs e)
                string fileName = listBox1.SelectedItem.ToString();
                Image img = Image.FromFile(fileName);
                pictureBox1.Image = img;

            private void btnSearch_Click(object sender, EventArgs e)
                LoadAllFiles(@"D:\MyPicture", this.listBox1);

            private void LoadAllFiles(string folderPath, ListBox listBox)
                DirectoryInfo dirInfo = new DirectoryInfo(folderPath);
                FileInfo[] fileInfo = dirInfo.GetFiles("*.jpg", SearchOption.AllDirectories);
                foreach (FileInfo file in fileInfo)
    Hope this helps. If you have any question with my code, please feel free to tell me.
