You should either us the Shopify integration for Google Merchant Center or use one of the shopping app in the Shopify App Store. Either one will make sure all your SKU information, including links to product images, are send to Google Merchant Centre.

Hi, thanks for your reply, is the Shopify integration accessible within Google Merchant Centre? I'm not keen to using the Shopify app at least for now
You make the connect inside Shopify. Your only option is an App, API connection or build your own shopping feed from scratch, which is time consuming.
This is an accepted solution.
@Antonello yes, I would avoid using the app if at all possible.... Are you using a google sheet to input your product info? You can find the image url for a product by right clicking the image and opening in a new tab - copy and past the url from there.
Hope that helps.
