I want to make a slideshow with transparent PNG images. How can I preserve the transparency of my images?

To preserve the transparency of your PNG images in your slideshow, first open ‘settings’ by clicking on the button with a screwdriver/spanner in the main toolbar.

Go to the ‘design’ tab by clicking on the button at the top of the window. Look into the right-hand column, and you will see a checkbox titled ‘Image fill color’. Uncheck this box in order to preserve transparent images.

Then click on ‘Apply’.
