[Pirate]

Like this :
this.pictureBox1.Image.Save("path_here")

Look also for the other overloaded functions of Save method where you can specify quality and format ...etc.

hi,
Iwant my picturebox image save to sql server.

umm I have no sql experience, so there might be a better way. I wrote this for you, it should work fine

I don't know of a more efficient way to convert an image to bytes, maybe someone else would comment (you could read the image pixels, byte by byte but that's a hassle)

// you need to do error handling 
		// (ie you could get a OutOfMemoryException if there 
		// isn't enough memory to create that byte buffer)
		//
		// you'd need these two namespaces:
		//		using System.IO;
		//		using System.Drawing.Imaging;
		private byte[] imageToBytes (Image img)
		{
			if (img==null)
				return null;

			byte[] buffer;
			MemoryStream ms = new MemoryStream();
			// Save as jpeg
			img.Save(ms, ImageFormat.Jpeg);
			ms.Position = 0;
			
			// will work fine UNLESS your image file is 
			// around 2GB or more in size hehe:-D
			int length = (int)ms.Length;
			buffer = new byte[length];
			ms.Write(buffer,0, length);			
			ms.Close();

			return buffer;			
		}
