Lemmy Support

Hello. I have already written my question, but your answer has greatly confused me.

I found how I can edit CSS, I just connected via Filezilla to SFTP and made the changes I needed in "/var/lib/docker/overlay2/5a3c8300921407520fee8ff0ad1d8dbe1be7234e56fb77b6c39398aada06629a/merged/app/dist/assets/css/themes".

But I'm stuck in the main problem. On the main page of the site, previews of topics are displayed in sequence:

<picture>
<source srcset="https://led.ural.wtf/pictrs/image/98fab6dd-f762-47ce-873a-cc8c5446c491.jpeg?format=webp&thumbnail=256" type="image/webp"><source srcset="https://lem.ouraw.wtf/pictrs/image/98fab6dd-f762-47ce-873a-cc8c5446c491.jpeg"><source srcset="https://lem.ouraw.wtf/pictrs/image/98fab6dd-f762-47ce-873a-cc8c5446c491.jpeg?format=jpg&amp;thumbnail=256" type="image/jpeg">
<img class="img-fluid thumbnail rounded" src="https://lem.ouraw.wtf/pictrs/image/98fab6dd-f762-47ce-873a-cc8c5446c491.jpeg" alt="" loading="lazy"></picture>

Thus, because of "&thumbnail=256" I can't stretch the image by more than 256px (in CSS), otherwise it starts to spoil the quality.

My question is: how can I remove this part of the code via SFTP?

You sent me Lemmy UI, but due to ignorance of Linux and lack of readme/faq, I don't even understand what to do with it. And is it really necessary? After all, I have already successfully established my Lemmy Federation.
