So you can do it in VBA. This can probably be ported to PHP quite simply.
Sub RemoveFirstPageAndAddHeaderFooter()
Dim d As Document
Set d = ActiveDocument
Dim pageOne As Range
Set pageOne = d.Bookmarks("\page").Range
pageOne.Select
Selection.Delete
d.Sections(1).Headers(1).Range.Text = "Some text"
d.Sections(1).Footers(1).Range.InlineShapes.AddPicture "C:\beigeplum.jpg", False, True
End Sub
...InlineShapes.AddPicture - , . , .Footers(1).Shapes.AddPicture, /, / ..
