@bigown jpeg and png. If it can be something more generic that addresses several formats it would help me even more. However jpeg and png are already enough.

You can get this information using the class Image, through the properties Height and Width.

var img = System.Drawing.Image.FromFile(@"c:\Path\1.jpg");
MessageBox.Show("Width: " + img.Width + ", Height: " + img.Height);

Can for some supported formats:

var imagem = Image.FromFile("teste.jpg");
var largura = imagem.Width;
var altura = imagem.Height;

In accordance with the documentation it is possible to open BMP, GIF, JPEG, PNG and TIFF.
