Answer 1

To filter only certain types of file use Filter Property

OpenFileDialog1.Filter = "Image Files (JPG,PNG,GIF)|*.JPG;*.PNG;*.GIF"; 

To get the file extension use the Path helper GetFileExtension

if (OpenFileDialog1.ShowDialog() == DialogResult.OK)    string ext = Path.GetExtension(OpenFileDialog1.FileName);
