Create a slideshow on Facebook with the images you have on your iPhone or Android device. The slideshow functionality is still in the experimental stage, which means your application may not have it. If you cannot see this option as described, your Facebook application does not support slideshows.
Steps

Step 1. Update the Facebook application
You can do this on an iPhone and on a device that runs Android. Since the slideshow functionality is still in the experimental stage, updating your app may activate it.
If you've seen this option in your Facebook app before, skip this step. The update may remove the slideshow functionality from your app

Step 2. Open Facebook
Tap the icon for the letter F which is inscribed on a dark blue background. This action will redirect you to your feed page if you've already signed in on Facebook.
- If you haven't signed in yet, enter your password and email address (or phone number) when prompted, then press Log in.

Step 3. Tap Speak Up
This is the text field at the top of the news feed. When you tap on it, a new publish window will open.

Step 4. Scroll down and tap Create slideshow
This is an orange icon at the bottom of the post entry field. When you click on it, the slideshow creation page will open.
If you do not see this option in your Facebook application, it means that it is not yet available for this one

Step 5. Tap Add Photos
This is a gray button located under the tab Pictures.

Step 6. Choose the images you want to add to the slideshow
Tap 3 or more photos (up to 10) to select them or tap the camera icon to take new photos.
- You can select images from your phone's photo album by pressing Add (or a similar option), until you select a maximum of ten photos, then press Ended.

Step 7. Tap Next
This option is in the upper right corner of the screen.

Step 8. Select the Music tab and choose a theme
Choose a theme you want to use for the slideshow. The credits you choose will determine the music and visual presentation of the slideshow.

Step 9. Add a title
Tap the tab Title and type in the designation you want to use for your slideshow.
Skip this step if you don't feel like adding a title

Step 10. Select Next
This option is in the upper right corner of the screen. When you click on it, the images will be compiled to create the slideshow you want.

Step 11. Tap Publish Where To share.
You will see this option in the upper right corner of the screen. When you click on it, your slideshow will be published on your Facebook profile page.
