如何使用此加密代码在表单中添加图像链接

这个代码应该如何在这里转换图像？我如何从bin文件夹中的文件夹定义图像？有人能帮我解决这个问题吗？我有20张照片和20张表格。。。

private static byte[] ConvertImageToByteArray(System.Drawing.Image imageToConvert, 
ImageFormat formatOfImage) 
{ 
byte[] Ret; 
try 
{ 
using (MemoryStream ms = new MemoryStream()) 
{ 
imageToConvert.Save(ms,formatOfImage); 
Ret = ms.ToArray(); 
} 
} 
catch (Exception) { throw;} 
return Ret; 
} 

//When you are ready to convert the byte array back 
//to an image, you can include the following code 
//in your method. 
System.Drawing.Image newImage; 

using (MemoryStream ms = new MemoryStream(myByteArray,0,myByteArray.Length)) 
{ 
ms.Write(myByteArray,0,myByteArray.Length); 
newImage = Image.FromStream(ms,true); 
// work with image here. 
// You'll need to keep the MemoryStream open for 
// as long as you want to work with your new image. 
} 

Image img = Image.FromFile("C:'mypath'myimage.png");  //load the file as image
pictureBox1.Image = img;  //use the image how you like
