I sometimes turn on inline images in my org file using code posted here.
,----
| ;; inline images in org files
| ;;iimage
| (require 'iimage)
| (setq iimage-mode-image-search-path (expand-file-name "~/"))
| ;;Match org file: links
| (add-to-list 'iimage-mode-image-regex-alist
| (cons (concat "\\[\\[file:\\(~?" iimage-mode-image-filename-regex
| "\\)\\]") 1))
| (define-key org-mode-map [(control c) ?i] 'iimage-mode)
`----
It might be an idea to make it a setting as to whether the target image
is inlined too. e.g I have a lot of links of this type:
[[file:../images/gud.png][file:../images/guds.png]]
And would like to only see the small preview png file in this case and
not the large one.
Has anyone implemented something like this or has the code above already
been merged into org?
regards,
r.

It would also be useful if you could specify the size of the image.
I'd like to use org-mode to organize pictures that I want to use for
LaTeX documents -- see the image, as well as the copyright info, etc.
But an image suitable for a presentation is way, way too large for
inline inclusion. Yet having to manually build thumbnail images
misses the point of easy organization!

A nice way to solve this would be to add a few customizable variables to iimage:
- iimage-max-size-x: do not display image is width > N
- iimage-max-size-y: do not display image is height > N
- iimage-scale-if-oversize: if non-nil, re-scale oversized image so that it fits
within iimage-max-size-x and iimage-max-size-y
Just my two cents. Best,
Felipe

Hi Felipe,
did ever try `M-x tumme' alias `M-x image-dired' ???
Displays thumbnails. And there is a possibility to annotate
files (does NOT write EXIF data):
Just press `c' and enter your comments. When ever you select
that image in the thumbnail window (or in dired even??) therafter,
the comment will show up again in the minibuffer.
You may even tag your images (`tt'), remove images from the
thumbnail-view (e.g. to sort them out to find a decision)
and more.
Hmm - emacs has some support for images, but I think it's not the ideal
environment for organising them yet.
How about some programm, that is able to handle a fair amount of
images and has features for organising them? They all create thumbnails
automatically and support tagging, anotations, editing, creation of
HTML-slideshows and and and...
I simply use http://gthumb.sourceforge.net/features.html.
Best Regards,
- Sebastian

Hi Sebastian,
The use case I think Lindsay refers to is not about tagging
images, but about displaying images inline in org-mode (as
muse-mode can do). Iimage does a lot of the work towards
that goal, but it would be nice to have some control about
what to do with oversized images (e.g., not displaying or
scaling them). That's my interpretation of Linday's comment
and a functionality I would like. Any volunteers?
Best,
Felipe

Hey all,
my first post to this list. This topic has been bugging me for some time also.
The following is a snippet of elisp that can be used to take a file
name in a buffer and paste the image file right below it. The image
is inserted just as any other character, and can be moved, yanked,
copied and/or pasted as such.
This only works for png, but it's easy enough to modify for jpeg, etc
as well. I often use this method in combination with various other
things to generate postscript/pstricks/latex diagrams, etc, and view
the results immediately.
(global-set-key (kbd "C-S-p") 'insert-png-wrapper)
(defun insert-png-wrapper ()
(interactive)
(setq oldmark (mark)) ; save old mark
(setq oldpoint (point)) ; and old point
(beginning-of-line)
(set-mark (point)) (end-of-line)
(setq filename (buffer-substring (mark) (point))) ; copy line
(newline 1)
(clear-image-cache) ; images are cached until cleared
(insert-image (create-image filename 'png))
)
If you load "eimp.el" as a minor mode, you can use the functions
"eimp-increase-image-size" and "eimp-decrease-image-size" to make the
image smaller or larger.
There's my 2.5 cents. Cheers.

eimp.el uses an external program (mogrify) to actually modify the image.
That's not what is wanted. The image should remain the same,
just be displayed in emacs in a smaller size

Here's a patch that introduces two custom options
org-display-inline-image-width, org-display-inline-image-height
and patches org-display-inline-images to respect them as
max width, height settings for inline images.
(Someone please defcustom them for me, I only know defvar syntax).
org-display-inline-images uses overlay-put.
(iimage.el uses text-properties, which are recommended in emacs).
(The refs below are (elisp) info nodes.)
Both overlays and text-properties use "Display Property",
"Other Display Specifications" to setup an image.
Of all "Image" formats, only "ImageMagick Images" (maybe XBM and PS)
support scaling.
That is, IF you build Emacs with ImageMagick (a big if indeed!)
So the patch uses scaling if (fboundp 'imagemagick-types)
and in this case you must call (imagemagick-register-types) in your .emacs;
else it uses a slice the top left corner (cropping the rest).

How to avoid line breakage in the patch?
Some source lines are naturally >80 chars and I wouldn't like to shorten them.
I posted from the web (http://post.gmane.org/post.php?group=gmane.emacs.orgmode)
I guess I should get an account and post from a real mail client?
Furthermore, the "Comments" at the patchwork server
(http://patchwork.newartisans.com/patch/526/)
mess up the patch, though the patch itself is ok

Better to use plain text emails from your client - sending from gmane
will result in messing up long lines.

I downloaded the patch and lines are not well wrapped - they are wrapped
the way patchwork displays it.
Could you resubmit your patch? I'm willing to test it.
Thanks!
