When you open your selected project, the image displayed at the top of the screen is referred to as the project banner image as shown below.
To change or remove the project banner, click on Edit Banner.
The following Edit Banner page is displayed.
Click on the banner to upload a new one. You can remove the existing banner by clicking on the bin symbol near the file name of the existing banner. You can upload .jpg, .jpeg, .png and .gif images only. Avoid images with a file size greater than 1MB. Enter a caption for the image, if required, in the Caption box. Click Save to save the changes.
You can also now crop a portion from the uploaded image to be displayed, as the banner. Other editing options are zooming in/out and rotating left/right.
However, these editing options don't help resize the banner image to the required dimensions. You will need to upload a banner with at least 1400 pixels in width. It can be any height.
Note - If your site homepage already has a banner, then when a new project is created, the site banner is auto-populated to the new project as a banner. You can either override that by uploading a new image or you can disable the option for site banner to be visible on project pages Appearance > Logo , icons and Images > disable the option 'Show site banner on project pages.
Note: All themes support project banners
