You can control how sponsor logos are displayed by selecting the appropriate logo shape in the sponsor settings. This helps ensure logos appear balanced and consistent, especially when using a mix of square and wide designs.
To adjust this, go to Manage > Sponsors, edit the sponsor, and open the Media tab. Use the Logo Shape dropdown to choose between Wide (default) or Square.
Please note that logo sizes are also optimised for better visibility, and you can further adjust their size through your theme settings if needed.
