            string[] fileEntries = Directory.GetFiles(@"C:\Projects_2012\Project_Noam\Files\ProteinPic");

            foreach (string fileName in fileEntries)
            {
                if (fileName.Contains(comboBox1.SelectedItem.ToString()))
                {
                    Image image = Image.FromFile(fileName);
                    // Set the PictureBox image property to this image.
                    // ... Then, adjust its height and width properties.
                    pictureBox1.Image = image;
                    pictureBox1.Height = image.Height;
                    pictureBox1.Width = image.Width;

I don't think you need to iterate through every file in the directory to acheive what you want

        Image image;

        string imagePath = System.IO.Path.Combine(@"C:\Projects_2012\Project_Noam\Files\ProteinPic", comboBox1.SelectedItem.ToString());
        if (System.IO.File.Exists(imagePath))
        {
            image = Image.FromFile(imagePath);
        }
        else
        {
            image = Image.FromFile(@"C:\Projects_2012\Project_Noam\Files\ProteinPic\Empty.png");
        }

        pictureBox1.Image = image;
        pictureBox1.Height = image.Height;
        pictureBox1.Width = image.Width;

string[] fileEntries = Directory.GetFiles(@"C:\Projects_2012\Project_Noam\Files\ProteinPic");

        if (fileEntries.Length == 0)
        {
            Image image = Image.FromFile("Path of empty.png");
            pictureBox1.Image = image;
            pictureBox1.Height = image.Height;
            pictureBox1.Width = image.Width;
        }
        else
        {
            foreach (string fileName in fileEntries)
            {
                if (fileName.Contains(comboBox1.SelectedItem.ToString()))
                {
                    Image image = Image.FromFile(fileName);
                    pictureBox1.Image = image;
