Sponsors are shared records. A page shows them only when you add a Sponsors block.
Open Sponsors and select Add Sponsor. Enter the sponsor's name. To add a logo, select Choose Image and choose an image from Media Library, or upload one. A logo of 400 px wide or more looks best. Add an HTTPS link if needed. Add a Sponsors block to a page to show the list.
Trackside chooses how many logos go in each row, so the rows are as even as possible. A short last row is centered.
Sponsor changes appear on published pages right away. A page draft still needs Publish before visitors see a newly added Sponsors block.
To delete a sponsor logo from Media Library, select Remove Image on the sponsor record first. Trackside protects images that a sponsor still uses.
