Thanks for post can you please use this is your logo image url
Hank here from Shopify. Really great question!
A great way at finding out your image URL's is within your admin! To do this, go to Settings > Files. In there you will see every image that has been uploaded to your admin, and the URL associated with it.
This is a sample from my test store as to what you can expect to see there. You can also search for file names there!
Let me know how you get on, or if you have any other questions!
All the best,
