GiveNow cover photos need to be rectangular and landscape. We recommend uploading an image that is 800 pixels wide x 310 pixels high.
There are two places to upload cover photos.
1. The cover photo for your organisation profile is uploaded in Org HQ > Details > Public Page > Edit logo & cover photo.
This is only seen by browsers of GiveNow when they click your organisation name in the search results.
2. The cover photo for your cause listing is uploaded in Org HQ > Causes & Donations > Manage Causes > Edit.
This is seen by GiveNow users when they are looking at the details of a cause.
