How to Manage Images in PowerPoint

Updated: August 2, 2026

Multimedia elements form the integral structure of a PowerPoint presentation. Images, in particular, provide visual context and reinforce the information presented on each slide. Effective image management (whether inserting new visuals, updating existing ones, or cleaning up outdated graphics) is imperative for maintaining professional and scalable presentations.

This guide demonstrates how to work with images programmatically using IronPPT.

Add Image

To add an image in a PowerPoint document using IronPPT, create a new document object (or load from an existing file). Then, create an image object from the Image class that references a file. Once the image is loaded, add it to the document and specify the slide number where it should appear. From there, image attributes can be altered using properties such as Height, Width, and Angle. Finally, export the document with the newly added image.

using IronPPT;
using IronPPT.Models;

// Create a new presentation document
var document = new PresentationDocument();

// Create and load an image from file
Image image = new Image();
image.LoadFromFile("image.jpg");

// Add image to the first slide (index 0)
var newImage = document.AddImage(image, 0);

// Rotate the image 180 degrees
newImage.Angle = 180;

// Save the presentation as a PPTX file
document.Save("adding-image.pptx");

using IronPPT;
using IronPPT.Models;

// Create a new presentation document
var document = new PresentationDocument();

// Create and load an image from file
Image image = new Image();
image.LoadFromFile("image.jpg");

// Add image to the first slide (index 0)
var newImage = document.AddImage(image, 0);

// Rotate the image 180 degrees
newImage.Angle = 180;

// Save the presentation as a PPTX file
document.Save("adding-image.pptx");

Imports IronPPT
Imports IronPPT.Models

' Create a new presentation document
Dim document As New PresentationDocument()

' Create and load an image from file
Dim image As New Image()
image.LoadFromFile("image.jpg")

' Add image to the first slide (index 0)
Dim newImage = document.AddImage(image, 0)

' Rotate the image 180 degrees
newImage.Angle = 180

' Save the presentation as a PPTX file
document.Save("adding-image.pptx")

Imports IronPPT
Imports IronPPT.Models

' Create a new presentation document
Dim document As New PresentationDocument()

' Create and load an image from file
Dim image As New Image()
image.LoadFromFile("image.jpg")

' Add image to the first slide (index 0)
Dim newImage = document.AddImage(image, 0)

' Rotate the image 180 degrees
newImage.Angle = 180

' Save the presentation as a PPTX file

Image Properties

Explore image property options in the table below.

Property	Description	Example
`Height`	Sets the height of the image in points.	`image.Height = 300;`
`Width`	Sets the width of the image in points.	`image.Width = 400;`
`Angle`	Rotates the image by a specified angle in degrees.	`image.Angle = 45;`
`Position`	Sets the position of the image on the slide using x and y coordinates.	`image.Position = (200, 200);`
`FrameShape`	Sets the frame shape of the image using ShapeType enum values.	`image.FrameShape = IronPPT.Enums.ShapeType.RoundRectangle;`

Modifying Added Image Properties

After adding an image to a slide, you can modify its properties to adjust appearance and positioning. E.g., using properties like Height, Width, and Angle to customize the image dimensions and rotation. Tweaking these settings lets you fine-tune how the image appears in your presentation.

using IronPPT;
using IronPPT.Models;
using IronPPT.Enums;

// Load an existing presentation document
var document = new PresentationDocument("existing-presentation.pptx");

// Create and load an image from file
Image image = new Image();
image.LoadFromFile("image.jpg");

// Add image to the second slide (index 1)
var newImage = document.AddImage(image, 1);

// Modify image properties
newImage.Angle = 45; // Rotate the image 45 degrees
newImage.FrameShape = ShapeType.RoundRectangle; // Set the frame shape to Rounded Rectangle
newImage.Position = (180, 180); // Set the position to coordinates (180, 180)
newImage.Width = 300; // Set the width to 300 points
newImage.Height = 300; // Set the height to 300 points

// Save the modified presentation as a new PPTX file
document.Save("modifying-image-properties.pptx");

using IronPPT;
using IronPPT.Models;
using IronPPT.Enums;

// Load an existing presentation document
var document = new PresentationDocument("existing-presentation.pptx");

// Create and load an image from file
Image image = new Image();
image.LoadFromFile("image.jpg");

// Add image to the second slide (index 1)
var newImage = document.AddImage(image, 1);

// Modify image properties
newImage.Angle = 45; // Rotate the image 45 degrees
newImage.FrameShape = ShapeType.RoundRectangle; // Set the frame shape to Rounded Rectangle
newImage.Position = (180, 180); // Set the position to coordinates (180, 180)
newImage.Width = 300; // Set the width to 300 points
newImage.Height = 300; // Set the height to 300 points

// Save the modified presentation as a new PPTX file
document.Save("modifying-image-properties.pptx");

Replace Image

Replacing an image is an intuitive task with IronPPT. First, load the presentation document and your new image into a fresh Image object. Then, target the image you wish to update by selecting its slide and index, such as Slides[0].Images[0] (for the first image on the first slide). Once complete, call the Replace method using the new image object and export the file.

using IronPPT;
using IronPPT.Models;

// Load an existing presentation
var document = new PresentationDocument("sample.pptx");

// Load the replacement image
Image replaceImage = new Image();
replaceImage.LoadFromFile("sample.png");

// Replace the first image found in the first slide
document.Slides[0].Images[0].Replace(replaceImage);

// Save changes (overwriting the original file)
document.Save("sample.pptx");

using IronPPT;
using IronPPT.Models;

// Load an existing presentation
var document = new PresentationDocument("sample.pptx");

// Load the replacement image
Image replaceImage = new Image();
replaceImage.LoadFromFile("sample.png");

// Replace the first image found in the first slide
document.Slides[0].Images[0].Replace(replaceImage);

// Save changes (overwriting the original file)
document.Save("sample.pptx");

Imports IronPPT
Imports IronPPT.Models

' Load an existing presentation
Dim document As New PresentationDocument("sample.pptx")

' Load the replacement image
Dim replaceImage As New Image()
replaceImage.LoadFromFile("sample.png")

' Replace the first image found in the first slide
document.Slides(0).Images(0).Replace(replaceImage)

' Save changes (overwriting the original file)
document.Save("sample.pptx")

Imports IronPPT
Imports IronPPT.Models

' Load an existing presentation

replaceImage.LoadFromFile("sample.png")

' Replace the first image found in the first slide
document.Slides(0).Images(0).Replace(replaceImage)

' Save changes (overwriting the original file)
document.Save("sample.pptx")

Remove Image by Index

The simplest way to remove an image is by its index position. Access the slide's image collection and use the Remove method with the zero-based index of the image you want to delete. This approach works well when you know the exact position of the image in the collection.

using IronPPT;

// Load an existing presentation
var document = new PresentationDocument("real_sample.pptx");

// Remove the first image found on the second slide
document.Slides[1].Images[0].Remove();

// Save the updated presentation
document.Save("removed-image.pptx");

using IronPPT;

// Load an existing presentation
var document = new PresentationDocument("real_sample.pptx");

// Remove the first image found on the second slide
document.Slides[1].Images[0].Remove();

// Save the updated presentation
document.Save("removed-image.pptx");

Before Image Removal

After Image Removal

Removing All Images

For scenarios where there needs to be a bulk deletion for all of the Image files in a document, we can use two for loops: once to iterate through all document pages, and twice to reiterate through and remove all the identified images per page. An example is shown below.

using IronPPT;
using IronPPT.Models;

// Load an existing presentation
var document = new PresentationDocument("real_sample.pptx");

// Remove all images from every slide
for (int s = 0; s < document.Slides.Count; s++)       // Loop through all slides
{
    var slide = document.Slides[s];                   // Get the current slide

    for (int i = slide.Images.Count - 1; i >= 0; i--) // Loop backward through images on this slide
    {
        slide.Images[i].Remove();                     // Remove each image
    }
}

// Save the updated presentation
document.Save("removed-images.pptx");

using IronPPT;
using IronPPT.Models;

// Load an existing presentation
var document = new PresentationDocument("real_sample.pptx");

// Remove all images from every slide
for (int s = 0; s < document.Slides.Count; s++)       // Loop through all slides
{
    var slide = document.Slides[s];                   // Get the current slide

    for (int i = slide.Images.Count - 1; i >= 0; i--) // Loop backward through images on this slide
    {
        slide.Images[i].Remove();                     // Remove each image
    }
}

// Save the updated presentation
document.Save("removed-images.pptx");

Imports IronPPT
Imports IronPPT.Models

' Load an existing presentation
Dim document As New PresentationDocument("real_sample.pptx")

' Remove all images from every slide
For s As Integer = 0 To document.Slides.Count - 1 ' Loop through all slides
    Dim slide = document.Slides(s) ' Get the current slide

    For i As Integer = slide.Images.Count - 1 To 0 Step -1 ' Loop backward through images on this slide
        slide.Images(i).Remove() ' Remove each image
    Next
Next

' Save the updated presentation
document.Save("removed-images.pptx")

Imports IronPPT
Imports IronPPT.Models

' Load an existing presentation
Dim document As New PresentationDocument("real_sample.pptx")

' Remove all images from every slide
For s As Integer = 0 To document.Slides.Count - 1 ' Loop through all slides
    Dim slide = document.Slides(s) ' Get the current slide

    For i As Integer = slide.Images.Count - 1 To 0 Step -1 ' Loop backward through images on this slide
        slide.Images(i).Remove() ' Remove each image
    Next
Next
