Best Companies Guide: How do I change a company's logo?

The best companies guide only gets released once a year and can only be updated by The Development team.

Should you require a change:

1. Create a zendesk ticket
2. Change the file name of the logo to the company id followed by Logo (123456Logo) no space between the id and Logo must have a capital 'L'
3. Attach the image to the zendesk ticket

Should you have any problems changing the name simply attach the image as it is and add the company id to the ticket.
