Trying to Use data-src attribute on Hubspot CDN imgs for lazyloading

SOLVE

Hi,

 

I am trying to make the images on our homepage lazyload to increase the page speed. I added the data-src html attribute to a few images and added the JS code in a seperate file and added it to the template. The links to the images are from Hubspot's files. The lazyloading does not seem to be working and I think the data src is the problem. Anybody have an answer to this?

 

Thanks

Here's another resource (from the guys at BluLeadz in 2018) that may still have value for you.

- see Lazy Loading Images on HubSpot

Hope that helps.

@benfoster it's possible, but you have to use your own custom modules instead of using the default HubSpot modules in order to control the image markup.

Hi @Mattg1 ,

 

Do you have links to the page you can share? Can you also share the code you are working with and what you have edited?

 

The more information, screenshots and details you can provide, the better the Community can assist.

 

Thank you,
Jenny

Same problem here. The issue that OP is describing is explained further here:

https://css-tricks.com/lozad-js-performant-lazy-loading-images/#article-header-id-3

 

From that article: "Also note we've removed the 'src' attribute of the image and replaced it with 'data-src'. This prevents the image from being loaded before the JavaScript executes and determines it should be."

 

Because all images are embedded using a "src" attribute, it's currently not possible (as far as I know) to implement lazy loading on Hubspot, because in order to do so, you have to execute Javascript before the images are loaded.

 

To fix this issue, there would need to be an advanced setting on images to use "data-src" instead of "src". Please implement this so that your users can lazy load images.

 

@jennysowyrda Please let me know if you have any questions.
