Yes, you have 2 ways:
- store the image path
- store the byte array in a memo (or blob depending on the DBMS) that you can retrieve with
Bitmap bmp = new Bitmap(_image);
TypeConverter bmpc = TypeDescriptor.GetConverter(bmp.GetType());
return (byte[])bmpc.ConvertTo(bmp, typeof(byte[]));
With "old" tecnologies you colud also store the image as OLE-resource, but I deprecate it.
