Be noted that the Show over Multiple Slides option depends on the duration of an object. After that, in the Timeline pane, click the All Slides button to view all the slides in the current project as well as the objects that span across multiple slides. Then, you can choose to place the object in the top layer or bottom layer of the stack order of slide objects. To do so, right-click the object > Show over Multiple Slides. This is useful when the object is a corporate logo or background music.

Note: You might want to make a single object appear in all the slides in the presentation. See Styling Multiple Objects for details. Then, you can edit each of these objects individually or style all of them in the same way. Once the file is selected choose the Change icon option and you will be able to rename. Once the batch processing finishes, the selected object will appear in all specified slides with the same properties. Click Insert ->Object->Create from file ->Browse. There are two ways to insert content objects into a PowerPoint presentation: Linked objects A linked object is updated if its source file is changed. For example, the range 3-6 indicates the 3rd, 4th, 5th, and 6th slides. The Insert Object box lists the object types you can use. Otherwise, use hyphens to indicate ranges. If you choose Specified Slides, separate the ordering numbers of slides by commas. Step 3: Specify the slides (2) into which you want to insert the object. Step 2: Select the object type (1) that you want.
