title: Using gatsby-image without GraphQL?
body: <p>Unfortunately, we are using Gatsby but foregoing many of its features like GraphQL. I would like to still use gatsby-image. Even though I won't be able to benefit from the resizing transformations, I'd like to get the other benefits like lazy loading and placeholders. Is there any way to do this by just passing in a url instead of passing in the result of a GraphQL query?</p>
