It is possible to display augmented reality images from the mobile application. These images can be imported in .jpg, .png or .gif format.
This is why it is important not to upload cover images of too large size and weight. This is even less relevant since cover images are usually displayed in small dimensions, for example at the size of a button or a logo. If a cover image is too large it will take longer to show in the app. We recommend using cover images ranging from 10KB to 100KB.
