LibreOffice Impress allows to create a nice Photo Album with a few clicks of the mouse. First, you open an empty presentation. Second, you access the feature with Insert > Media > Photo Album. Third, you press the Add button to select your pictures from your hard disk. Fourth, you choose your options (slide layout, caption, aspect ratio) and then press Insert Slides to create the Photo Album, and – in a few seconds – you get the final product.
