Excel userForm: cant resize .jpg graphic, and .png graphic 'invalid'

Hi,
This is my first experience of importing pics into Image ctls.
Both of the two pics studied here insert into an xl worksheet cell via .Shapes.AddPicture, without a problem. The xl cell height was for a font of Calibri, font 11 (so the final imported image size was quite small).

The only code within the attached xl file is shown below.
The attached .png and .jpg graphics files should be in same folder as xl file.
Run the UserForm from the activeX cmd on 'sheet 1'.

Please can you show me how to get the jpg image to fit into the image ctl set before initialization to 42x48 and which expands to [114 x 132 (HxW)] when .Autosize is False?

I found no helpful additional Image.properties to help me forward.

When pathPic = "openVisio.png   the bug report is: 'graphic is invalid'.
What graphic types are permitted?

Thanks in anticipation,
Kelvin

Private Sub UserForm_Initialize()
    Dim pathPic As String
   
    pathPic = "Question Relationships.jpg"
    'pathPic = "openVisio.png" '''>>>>> "invalid picture" why, what file types are valid?
    'pathPic = "hello.jpg" '>>>> "file not found" - correct it was deliberately not there
   
    Debug.Print "pathPic = "; pathPic
    Image1.Picture = LoadPicture(pathPic)
    Image1.AutoSize = False 'True makes the control expand, not the graphic shrink
    Image1.Height = 42
    Image1.Width = 48
   
End Sub
