Load Pictures From Folder Into Image Control

I am able to work out a code to upload pictures from my files using this:

Option Explicit

Private Sub cmdfind_Click()
Application. ScreenUpdating = False
Dim strfind As String
Dim rsearch As Range
Dim strfolder As String
Dim strname As String
Dim strpic As String
Dim b As Range
Set rsearch = Worksheets("m").Range("ap3", Range("ap65536").End(xlUp))
'define path to images
strfolder = "F:SEC FILESMAC2PIC"
'get data from userform
strname = frmsearch.txt201.Value
'check if pic exists
strpic = strfolder & strname & ".jpg".......................

How do i avoid the 'File Not Found' error if the picture is not available in my file folder?
