' Stretches the image to fit the pictureBox.

PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage

'MyImage.Size.ToString will look something like this: {Width=800,Height=600} -- The width starts in the 8th

'position and the height starts in the 9th position after the comma.

Dim a As Array = Split(MyImage.Size.ToString, ",")
