As a starting point I wanted to share this resource with you written by @stefen which speaks to lazy loading for images in HubSpot. Stefen, do you have any further tips or tricks for @creativepayal17?
how I can add the lazy loading in HUBSPOT drag and drop images module and CTA modules ?
@creativepayal17 I'd recommend creating your own Lazy Loading Image custom module and use that instead of the standard image module. This will give you complete control of the markup of each image tag.
