Hey hey :) currently i load an image via image()
Is it somehow possible to get information about the image? Like detected "format"?
And the loaded bytes?

The detected format is completely transparent, sadly no way to get that at the moment.

What you can get back out is what you provide (source, alt-text, etc.); from there you could for example look at the file-extension.
You can't get the loaded bytes, but you can read the source separately and inspect them that way.

Note that image() also accepts the bytes type as a source. You'd need to handle that separately, but in that case, you can indeed get the bytes back out directly.

if you have experience with other languages you could probably package an existing library as a plugin, but yes I don't think something like that exists yet.
