How to "Reset Picture" in Power point Slide using VBA macro?

I am generating power point presentation using Excel. The macro is running excel. It is working perfectly fine. Issues is the Excel macro pasted the pictures with strange format. I have to use manually the command of "Reset Picture" by right clicking on each picture-->Picture format--> Reset picture

Is it possible to make a macro power point which can do the reset picture command automatically for me?

THanking you advance Best regards

 apic = ThisWorkbook.Sheets("Jan 2015").Range("aa" & CellNr).Value
 mpic = ThisWorkbook.Sheets("Jan 2015").Range("ab" & CellNr).Value

If ThisWorkbook.Sheets("Jan 2015").Range("z" & CellNr) > 0 Then
