Before resizing remove Anchor (set it to zero) after resizing set it back to its value.

FOR i = 1 TO thisform.pf.Pagecount
    thisform.pf.Pages[i].addobject("img_back","image")
    WITH thisform.pf.Pages[i].img_back
      .Anchor = 0 && Here
      .ZOrder(1)
      .left = 0
      .top = 0
      .Height = Thisform.pf.Height
      .Width = Thisform.pf.Width
      .Anchor = 15
      .picture = "D:\foxprogs\foxbib\images\blueform.png"    
    Endwith
Next
