Is there anything I can use directly in XSL (this one stylesheet) that
will just give me the filenames of these images? I can do some other
preprocessing stages and build an xml file with all these images

doing all of this heavy lifting and decision making.

XSLT 3/XPath 3 has a function uri-collection and I think with Saxon if
you use that function with e.g. ?select=(*.jpg|*.png) it gives you a
sequence of file URIs to the files without the need to process the
binary file contents.

Looking at
https://www.saxonica.com/html/documentation12/sourcedocs/collections/collecti
on-directories.html,
it might help Saxon if you not only provide the file suffix in the
select "parameter" behind the question mark but also the content-type
for the image file type you are looking at.
