Adding a logo and banner image to your overview is one of the first things you should do when you log in to CrowdWorks. This will help your company to be identifiable, and you can bring a bit of your brand into your profile. You can do this either via settings or on the profile page.
Use png or jpeg files.
The best size for the banner is bigger than 1825x450px
The logo is cropped to be a circle. Therefore, it is good to have some space around your logo. Then it will be fully visible.
