Select "Choose image" to upload a logo and/or a favicon

Make sure you upload a logo at double the size you need. This will ensure it looks good on high resolution devices.

This means that if you want a 50x50 logo, upload a 100x100 version. Timelapse will handle the resizing.

The favicon should be a square image and at least 128x128px in size.
