念のためコードも書いておきます。
挿入部分のコードは以下のとおりです。
With .Pictures.Insert(ThisWorkbook.Path & "\" & folderName & "\" & myFileName)
.CopyPicture
.Delete
Worksheets(shName).Paste
End With
With Selection
.Top = Worksheets(shName).Cells(i, toClm).Top
.Left = Worksheets(shName).Cells(i, toClm).Left
.Height = Worksheets(shName).Cells(i, toClm).Height
.Placement = xlMoveAndSize
End With
