<img src="data:image/svg+xml…" ?

Hi

I use Photonic on 2 webites, one works but not the other one.

The img tag in the webite that works is like this: https://i.postimg.cc/8C874G2g/works.jpg

The img tag in the webite that do not works is like this: https://i.postimg.cc/6Qdy1SK2/donotworks.jpg

when I deactivate Photonic the src=”data:image/svg+xml…” disappears…

I don’t undertand where comme from this data:image/svg+xml…

Thanks
