To add an interactive slideshow to a Blio ebook, draw a picture box on your active layout.
In an external folder, number the picture files in the order you want them to appear. Using the Save Picture feature (File > Save Picture), resize and crop the pictures so that when you import them at a scale of 100%, they fit perfectly in the picture box. Select the picture box and choose Item > Digital Publishing > Edit Interactivity. Choose slideshow from the Type drop-down menu in the Interactive Attributes dialog box. Click Attach and select the folder that contains the picture files, then click OK.
