[BUG] Html making 'ltximg' directory in source folder, rather than out folder [9.7.11 (release_9.7.11 @ /home/pranshu/Documents/appsource/emacs/lisp/org/)]

[BUG] Html making 'ltximg' directory in source folder, rather than out folder [9.7.11 (release_9.7.11 @ /home/pranshu/Documents/appsource/emacs/lisp/org/)]

[Pranshu Sharma]

When doing:
(org-export-to-file 'html "~/new/path/thing.html")
and the file option has the path "~/other/path/file.org", the 'ltximg'
directory is made in "~/other/path/", which is not intutive, or useful
behaviour.


(the option 'tex' is set to 'dvisvgm')

Confirmed.
Something like the attached patch should fix this.

However,
1. It will be a breaking change
2. We are in the process of rewriting LaTeX preview backend, so this may
   need to be addressed differently

I'd like to hear from Timothy or Karhik on this first.
