I'm making a presentation with only images and captions from events as a slideshow, one slide per event. One slide can contain 2-8 images from the same event.

I would like to be able to rezise and arrange all images in one slide or the whole presentation. But I can't figure out how to find or select all images.

I know how to insert a shape of a certain size, but I don't know how to find the images already inserted, and resize them.

function plassering() {

var slide = SlidesApp.getActivePresentation().getSlides()[6];

var shape = slide.insertShape(SlidesApp.ShapeType.RECTANGLE);

shape.setLeft(14).setTop(14).setWidth(690).setHeight(510).setRotation(0);

Logger.log('Left: ' + shape.getLeft()

                + 'pt; Top: ' + shape.getTop()

                + 'pt; Width: ' + shape.getWidth()

                + 'pt; Height: ' + shape.getHeight()

                + 'pt; Rotation: ' + shape.getRotation() + 'u00B0.');

}

The caption should be on top av all the images.

I got it! This is for the current slide, but I guess I may do the same for all the slides, one at a time.

function rearrangeImages() {

  //Select current page

  var currentPage = SlidesApp.getActivePresentation().getSelection().getCurrentPage();

  var slide = currentPage;

  //Get all the images of CurrentPage

  var pageElements = slide.getImages();

  //For each image, change the size and position

  for (var i = 0; i < pageElements.length; i++) {

    pageElements[i].select(true);

    var image = pageElements[i];

    var imgWidth = image.getWidth();

    var newWidth = 690; 

    var imgHeight = image.getHeight();

    var forhold = imgHeight/imgWidth;

    var newHeight = forhold*newWidth;

    image.setLeft(14).setTop(14).setWidth(newWidth).setHeight(newHeight).setRotation(0);

    var ui = SlidesApp.getUi();

   // ui.alert (imgWidth);

    pageElements[i].select(false);

  }

}
