We know that high-quality images lead to higher engagement, so the new view requires all event opportunities to have an image. If you do not configure an image, we will surface a default GivePulse image or reuse your group's cover image.
You'll see the option to add an image to your event under Advanced > Logos. For best results, upload an image that is 908 px by 318 px. Note that on the group view of events, there will be a 50px cropping on the left and right sides of the image (see the purple section in the image below), so make sure you don't have any text within 50px from the left and right borders of the image.
