How to Add Images to PowerPoint Slides in Python

Images in Aspose.Slides FOSS are embedded as picture frames, shapes that hold an image and can be positioned, resized, and styled like any other shape. The image data is stored once in the prs.images collection and referenced by the frame.

Prerequisites 

pip install aspose-slides-foss

Add an Image from a File 

from aspose.slides_foss import ShapeType, PictureFillMode
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]

    # Load image into the presentation's image collection
    with open("photo.jpg", "rb") as f:
        img = prs.images.add_image(f.read())

    # Add a picture frame at (x=50, y=50, width=400, height=300) in points
    frame = slide.shapes.add_picture_frame(
        ShapeType.RECTANGLE,
        50, 50, 400, 300,
        img,
    )

    prs.save("with-image.pptx", SaveFormat.PPTX)

The add_picture_frame signature:

add_picture_frame(shape_type, x, y, width, height, image) → PictureFrame

All dimensions are in points (1 point = 1/72 inch). For a standard 13.33 × 7.5 inch slide the coordinate space is 960 × 540 points.

Add an Image from Bytes

If you already have the image as bytes (e.g., downloaded from a URL or read from a database):

import aspose.slides_foss as slides
from aspose.slides_foss import ShapeType
from aspose.slides_foss.export import SaveFormat

image_bytes = open("logo.png", "rb").read()  # or any bytes source

with slides.Presentation() as prs:
    img = prs.images.add_image(image_bytes)

    prs.slides[0].shapes.add_picture_frame(
        ShapeType.RECTANGLE,
        200, 100, 300, 200,
        img,
    )
    prs.save("logo-slide.pptx", SaveFormat.PPTX)

Control the Fill Mode

The picture_fill_format on a PictureFrame controls how the image fills the frame bounds:

from aspose.slides_foss import ShapeType, PictureFillMode
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    img = prs.images.add_image(open("texture.png", "rb").read())
    frame = prs.slides[0].shapes.add_picture_frame(
        ShapeType.RECTANGLE, 50, 50, 600, 350, img
    )

    # STRETCH: scale image to fill the frame exactly (default)
    frame.picture_format.picture_fill_mode = PictureFillMode.STRETCH

    # TILE: repeat the image in a grid pattern
    # frame.picture_format.picture_fill_mode = PictureFillMode.TILE

    prs.save("filled.pptx", SaveFormat.PPTX)
PictureFillModeBehaviour
STRETCHScale the image to fill the frame, ignoring aspect ratio
TILERepeat the image as a tiled pattern
TILE_FLIPTile with alternating horizontal/vertical flips

Add Multiple Images to Different Slides 

import os
from aspose.slides_foss import ShapeType
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

image_files = ["slide1.jpg", "slide2.jpg", "slide3.jpg"]

with slides.Presentation() as prs:
    layout = prs.slides[0].layout_slide

    # Ensure enough slides exist
    while len(prs.slides) < len(image_files):
        prs.slides.add_empty_slide(layout)

    for i, path in enumerate(image_files):
        if not os.path.exists(path):
            continue
        img = prs.images.add_image(open(path, "rb").read())
        prs.slides[i].shapes.add_picture_frame(
            ShapeType.RECTANGLE, 0, 0, 960, 540, img
        )

    prs.save("multi-image.pptx", SaveFormat.PPTX)

Count Images in an Existing Presentation 

import aspose.slides_foss as slides

with slides.Presentation("with-image.pptx") as prs:
    print(f"Presentation contains {len(prs.images)} image(s)")

The prs.images collection is shared across all slides: the same image bytes are stored once even if the picture frame appears on multiple slides.
