Replace a Picture in MS Word header with another in VBA

Question

Using MS access I need to open a word document and change certain images within the header. Whilst I have the code to find and replace any text that I need, I do not quite understand how to replace an image keeping it to a specific width and height.

The header within the Word document is constructed using a basic table with 3 columns as depicted below. The image in the right hand column will need to change for a specific logo.

I have managed so far to add an image to the document using the following code which gives the expected result...

With WordDoc.StoryRanges(wdPrimaryHeaderStory)
  .InlineShapes.AddPicture FileName:="test.jpg"
End With

I understand that this is due to me not specifying a specific location, size etc but I am struggling to find resources which would instead allow me to either remove and add a new image to the right column or just swap the images out.
