Trying to tap into the resize image feature for our blog feed to serve up a better image size for performance: [HubL functions - HubSpot docs](https://designers.hubspot.com/en/docs/hubl/hubl-supported-functions#resize-image-url)

Currently using this approach:

`<img src="{{ resize_image_url(content.post_list_summary_featured_image, 740 ) }}" width="740" class="post-listing img">`

the returned src images are full size though - anyone happen to have any ideas on how to remedy?

Hi @Anonymous,

Thanks for posting your question.

I found some ideas related to this and a great explanation related to the resize option, [here.](https://community.hubspot.com/t5/CMS-Development/Featured-image-sizes/td-p/26673)

I hope these ideas help you achieve your resized image.

Regards,

Kira

@Anonymous it looks like you’re using it correctly. You could try adding all 3 arguments to see if that helps. e.g.:

`<img src="{{ resize_image_url(content.post_list_summary_featured_image, 0, 0, 740 ) }}" width="740" class="post-listing img">`

I have noticed sometimes if the filename has a bunch of funky characters in it or if it’s an animated GIF, it will not resize the image. Hope that helps!

{{ resize\_image\_url(content.post\_list\_summary\_featured\_image, 0, 0, 740) }} should be correct.  
For a long time I didn’t think this function was working, but what I noticed one day is it can take a couple of minutes before the new sized image is available, in which case it will return the full sized image until then - so no broken images while that occurs.
