Assuming jpeg when it's not certain

text2image_stablediffusion for example returns png images. You can detect the mimetype from the content using a php function I forgot the name of :D

Ah, I see you're converting to jpeg here https://github.com/nextcloud/text2image_helper/blob/main/lib/Service/Text2ImageHelperService.php#L128-L133

mmh. I'd rather we keep the original format and stay agnostic

Depends highly on the provider. OpenAI provides PNGs that are 5mb per pop. The idea here was to guarantee consistent compression and file size.

Alternatively, you can also use the preview manager to create smaller previews: https://nextcloud-server.netlify.app/classes/ocp-ipreview#method_getPreview

With OpenAI, for example, it's not about resolution (max 1024x1024) but rather just the compression. I get that I can also use the preview manager for the compression. But given that image compression is relatively inexpensive (especially since it's done only once per file and not for every request here) I'd tend to think using the php built-in methods makes sense here. Would you agree?
