Resources.ResourceManager.GetObject wouldn't provide object

问题

I cannot figure out, or google an answer, why pulling an image from project resources this way doesn't work:

    Dim MIIcon As Image
    Dim obj As Object = My.Resources.ResourceManager.GetObject("Item22")  'file: "Item22.png"
    MIIcon = DirectCast(obj, Image) 
    Me.PictureBox2.Image = MIIcon

The obj is nothing. Neither it works with file extension included. While this (direct path) works (but it wouldn't when deployed, of course):

    Dim MIIcon2 As Image
    MIIcon2 = Image.FromFile("C:\Users\****\documents\visual studio \Projects\******\Resources\Item22.png")
    Me.PictureBox3.Image = MIIcon2

Did I missed something? I must have done that couple of times in past. This test code is run at Form1_Load() event. Obviously, I can see the Item22.png in my resources in VS.

EDIT

I added the sample image using Visual Studio: Project Resources context menu -> Add... -> Existing item

The only way to make an image accessible through My.Resources is to add it to your project's .resx file. The Resources folder exists only so that VS has a way of referencing the resources at design time. Adding files to it will not include them in the actual resources.

To add a new resource:

Right-click your project in the Solution Explorer and press Properties (fig. 1).
Go to the Resources tab (fig. 2).
Drag and drop your resources into VS (fig. 3).
