Since PicturesToExe Deluxe 8.0 you can easily link images on a slide.

For example, you want to create a reflection of an image.

Add a new image to the Slide list. Open Objects and animation editor.

You see that image has option “Main object: 1”.

Copy and paste this object. It will have same option “Main object: 1”. Both images are linked:

If you replace file name of one image object, another linked image also will be replaced.

See the Demo:

This demo project shows another use for this new great feature. First slide contains 4 objects with same image file name and adjusted Canvas size to create an animation. You can easily replace all these images in one click.
