Head to your "Company Settings".
Click on "Upload your logo" button and choose the image that you wish to use.
Your logo needs to either be a .jpg file, or a .png file.
The image size fits into a space of 600px wide by 150px high.
If you wish to have multiple images as your logo, you will need to first combine them and then upload them as a single image.
The image will be centrally aligned (square images will appear in the middle, as per the image below).
Send us your logo, and we will happily resize and reformat it for you, and then send it back for you to upload.
