Hi,
I would like to use shr to render an HTML document with images. These
images are only accessible when logged in, so I need cookies to be sent
by shr. Unfortunately, `shr-tag-img` explicitly pass t to
INHIBIT-COOKIES when calling `url-queue-retrieve`. Several calls to
`url-retrieve` in the same file also inhibit cookies.
Why is that so? Can we make that configurable through, e.g., a new
option `shr-img-inhibit-cookies` or similar?
Best,

It's an artefact from when shr was used mainly for rendering Gnus
articles, I think.

Yes, I think that sounds fine. eww, for instance, should (by default)
send cookies when retrieving images, for instance, but it needs to be
tempered by allowing not sending cookies to third-party images and the
like. The entire eww cookie/referer thing needs a makeover, but that's
a different story.
But, yes, adding a `shr-use-cookies' variable to be bound before calling
`shr-insert-document' would be good.
