Hello,

imgix used with prismic seem not working for us.  
In compiled html, url of image is in this format :

[https://images.prismic.io/repo\_name/XXXX.webp?auto=compress,format](https://images.prismic.io/repo_name/XXXX.webp?auto=compress,format)

When changing size of image, I don't see any difference from network image size transfert.  
Note that image format was converted to image/avif by imgix server.  
Auto compress seem not working at all. The size is exactly the same in networks transfert.  
Any idea about ?

Thank you

Hi @ali,

Could you show me what transformations you're applying and how you're applying them? And could you share an image URL with me so I can test it myself?

(Feel free to DM the image URL if you don't want to share it publicly.)
