Answer 1

using Picture as Shape object and editing it's properties

Sub ajustar2()
Dim imagen1 As Slide, pic As Shape
Set imagen1 = ActivePresentation.Slides(1)
Set pic = imagen1.Shapes.AddPicture(FileName:="D:\INFORMES\PILAS\hazard.png", _
            LinkToFile:=msoTrue, SaveWithDocument:=msoTrue, Left:=10, Top:=75, _
            Width:=433, Height:=330)
With pic
.Line.Weight = 5
.Line.ForeColor.RGB = RGB(255, 0, 0) 'choose RGB color combination
.ZOrder (msoSendToBack)

End With
End Sub
