In this article I will explain how you can add all the images from a target folder to a power point presentation using VBA.

Step 1: Get all Files in a directory

The first step is to write a code that will retrieve all files in a directory. This can be done using the function below:

Private Function GetAllFilesInDirectory(ByVal strDirectory As String) As Variant
Dim objFSO As Object
Dim objFolder As Object
Dim objFile As Object
Dim arrOutput() As Variant
Dim i As Integer

'Create an instance of the FileSystemObject
Set objFSO = CreateObject("Scripting.FileSystemObject")
'Get the folder object
Set objFolder = objFSO.GetFolder(strDirectory)
ReDim arrOutput(0)
i = 1
'loops through each file in the directory and prints their names and path
For Each objFile In objFolder.Files
 
    'print file path
    arrOutput(i - 1) = objFile.Path
    ReDim Preserve arrOutput(UBound(arrOutput) + 1)
    i = i + 1
Next objFile
   ReDim Preserve arrOutput(UBound(arrOutput) - 1)
GetAllFilesInDirectory = arrOutput
End Function

The function receives as input a directory path and returns an array of all files in the directory:

Dim arrFilesInFolder As Variant
arrFilesInFolder = GetAllFilesInDirectory("C:\Users\Public\Pictures\Sample Pictures")

Step 2: Creating a new Slide and Adding an Image:

The function below receives as input the path of an image file and:
1- Creates a new slide.
2- Inserts the image.

Private Function AddSlideAndImage(ByVal strFile As String)
Dim objPresentaion As Presentation
Dim objSlide As Slide

Set objPresentaion = ActivePresentation

Set objSlide = objPresentaion.Slides.Add(1, PpSlideLayout.ppLayoutChart)
Call objSlide.Shapes.AddPicture(strFile, msoCTrue, msoCTrue, 100, 100)
End Function

Calling Context:

Call AddSlideAndImage("C:\Users\Public\Pictures\Sample Pictures\Chrysanthemum.jpg")

Putting it All Together:

Sub main()
Dim i As Integer
Dim arrFilesInFolder As Variant
arrFilesInFolder = GetAllFilesInDirectory("C:\Users\Public\Pictures\Sample Pictures")

For i = LBound(arrFilesInFolder) To UBound(arrFilesInFolder)
    Call AddSlideAndImage(arrFilesInFolder(i))
Next
End Sub
Private Function GetAllFilesInDirectory(ByVal strDirectory As String) As Variant
Dim objFSO As Object
Dim objFolder As Object
Dim objFile As Object
Dim arrOutput() As Variant
Dim i As Integer

'Create an instance of the FileSystemObject
Set objFSO = CreateObject("Scripting.FileSystemObject")
'Get the folder object
Set objFolder = objFSO.GetFolder(strDirectory)
ReDim arrOutput(0)
i = 1
'loops through each file in the directory and prints their names and path
For Each objFile In objFolder.Files
 
    'print file path
    arrOutput(i - 1) = objFile.Path
    ReDim Preserve arrOutput(UBound(arrOutput) + 1)
    i = i + 1
Next objFile
   ReDim Preserve arrOutput(UBound(arrOutput) - 1)
GetAllFilesInDirectory = arrOutput
End Function

Private Function AddSlideAndImage(ByVal strFile As String)
Dim objPresentaion As Presentation
Dim objSlide As Slide

Set objPresentaion = ActivePresentation

Set objSlide = objPresentaion.Slides.Add(1, PpSlideLayout.ppLayoutChart)
Call objSlide.Shapes.AddPicture(strFile, msoCTrue, msoCTrue, 100, 100)
End Function
