Yes, anything you can do in the designer can be done at runtime. Just have the code execute inside the Form Load event.

An example would be:
CODE

Dim newPictureBox As New PictureBox

newPictureBox.Image = Image.FromFile("C:\pathToYourImage\filename.jpg")
newPictureBox.Visible = True
newPictureBox.Top = 20
newPictureBox.Width = 100
newPictureBox.Height = 50
newPictureBox.Left = 10
'add control to form
Controls.Add(newPictureBox)

one question i have about that is what will the name of that picture box be

The name of the PictureBox is the name of the object given in the Dim statement, in this case newPictureBox.

To create an array of controls you must initialize each control independently of the others. That is why you cannot use the New keyword when declaring the array of controls.
CODE

Dim test(5) As PictureBox

test(0) = New PictureBox
test(1) = New PictureBox
.
.
.etc..
Controls.Add(test(0))
Controls.Add(test(1))


Don't forget, if you create your controls in code then you must handle setting the properties in code like I showed you in the previous post.

Test(1).Image = Image.FromFile("C:\documents and settings\rob crampton\desktop\red chip.tiff"
test(1).Width = 51
test(1).Height = 53
Test(1).Top = 373
Test(1).Left = 220
Test(1).visible = true
controls.Add(Chip(1))

but it highlighted
CODE

test(1) = New Picturebox

NullReferenceExeption was Unhandled

newPictureBox.Height = 50

Controls.Add(newPictureBox)


What happens when the project is sent to a different user or computer? The path name to the picture will not be the same. How can this be overcome?
