Applied, onto main. Fixing the spotted typo and replacing
`pixel-fill-width' with `frame-char-width' that is available in Emacs
26.

This looks fantastic!  +1 for using the Fill Column by default.

Emacs will actually scroll partially when the image is taller than
window height. But not otherwise.
Changing this is not trivial.

[Christopher M. Miles]

This is an acceptable solution for large width image. I propose this RFC too.

We cannot automatically resize images in Elisp. At least, I know no good
way to do it reliably.

But we can try to improve the defaults for wide images.

See the tentative patch.

In org-download you can specify html attributes for the attached image,
see link

https://github.com/abo-abo/org-download/blob/master/org-download.el#L178-L184

It's not a prompt, it's a template and you can fill the alt description.

Re: feature request: easy embedding of images

[Jude DaShiell]

To help accessibility it would be useful when an image was dragged into
org-mode if the user got prompted for an image description that gets
associated with the image in org-mode.  Some images are art work and those
should get alt="" tags if a user fails to provide a description but only
after asking if this image is art work or something that needs a
description.  If a description is provided that should go between the
quotes in the alt="" tag.

Russell mentioned a package and pointed to the image issues related to
Emacs, not Org.

I want to suggest the package https://github.com/abo-abo/org-download
which I use all time, for dragging and dropping images and for taking
screeshots.

Have you looked at org-attach-screenshot?

https://github.com/dfeich/org-screenshot

It uses org-attach and calls out to take a screenshot.

I do the same with some local function's I wrote a while ago. It works
very well for me. I run M-x my/org-screenshot, and after 3 seconds it
will use Imagemagick's "import" command to allow me to select a region
to screenshot and saves it to a filename I prepared.

I do this daily, many times each day.

This is Emacs, not Org. Perhaps someone knows how to adjust that.

Mine jumps too, but again that's Emacs, not Org.

I can't answer that. Drag and drop functions depend on your
platform. Does anything else in Emacs use drag and drop?

I do save all of mine to the same directory as my org file in
.org/Filename.org.screenshotMMDDHHMMSS.png. It means I can easily
know what files below to my org document.

Of course it's valuable, and already implemented. I think you're
asking more about refining how you use it.

feature request: easy embedding of images

[Alexis Gallagher]

Hello, my fellow org-mode lovers,

This is a feature request — or failing that, a request for advice on a settings 
configuration which could produce this functionality now. 

I wish org-mode had the ability to attach images to notes, display them inline, 
and have that work well. By “work well” I mean a few specific things:

•   the image is automatically resized to maintain aspect ratio and 
fit horizontally with a civilized margin, so that I can resize my emacs window 
without the image disappearing or swamping the other content. 
•   you can still scroll the window one line height unit at a time, 
without the entire image being scrolled as if it were one giant line, breaking 
scrolling, as seems to happen on my emacs (version 28.x on Linux)
•   drag and drop, so I can add the image by dragging it in, for 
instance from a screenshot tool or from an image on a web page.
•   sensible defaults for storing the images bundled with notes and 
keeping the two associated, so that I don't subsequently live in fear of ever 
moving my org files

Why is this valuable, to me at least? I use org to take notes all day, during 
meetings, on reading matter, in the development of my own thoughts. Embedding 
images would let me collect every kind of resource I can't reproduce by typing 
or copy and pasting text — photos of slides during presentations, photos of 
whiteboard,  key snippets from websites, handwritten notes and equations, etc..
