While your Flipbook is loading you will see a preloader image. Unfortunately not everyone is going to be on a high speed fiber connection, so some will see a preloader image.
The iPaper logo is displayed by default, but you can insert a preloader image of your own choice.
The image will be displayed in its actual size (only downscaling).
So, unless you want it to take up the entire screen, consider making the Preload image less than 500px wide.
Also, smaller size = smaller filesize
PNG is lossless and offers transparency which will make your logo/image function better on any background.
GIF is an option
If you want your Preloader to come alive, you can use an animated GIF
How to insert a Preloader image:
Let's add one! Start by adding the image or GIF you want to use to your media folder. From there it's easy:
Navigate to your Flipbook or folder of choice
Go to settings
Add image or GIF from media folder!
That's all there's to it. Now you can just hope people have really slow connections, so they can watch your cool new preloader!
