We would highly recommend an image with little to no text and a very clear motif depicted in the centre.
Regarding the formatting of your chosen image, you'll need to supply an image in JPG, PNG or GIF format with a dimension of ideally 1440x600 pixels or larger.
If using an image that does not belong to yourself or organisation, please make sure you have explicit permission from the image owner before adding it to your event.
Alternatively you can use our Unsplash intergration, giving you a wide range of professional photos and images to use as your event banner. All you need to do is search within the input field and select and crop the image as required!
