Hi,

I'm using inline images a lot in my org-files, but sometimes, the inline
image disappears and I need to do a  (org-display-inline-images) again.
I need to look in more details when does this really happen.

But what annoys me is that I added a : #+STARTUP: inlineimages, and it
doesn't seems to work…

Any ideas ?

Another nice thing would be a way to reduce the image size, just like
thumbnails. Do you think it can be done ?

J.

Ok, let us know.

I cannot reproduce it.

What version of Emacs/Org are you using?

Not currently -- see the docstring of the create-image function in
Emacs.  I have vague memory of work beeing done in this area in Emacs,
but AFAIK this is not yet implemented.

If the imagemagick backend is used for displaying the image in question,
then resizing is possible by providing a :width or/and :height spec.

,----
|    Images loaded with ImageMagick support a few new display
| specifications:
| 
| `:width, :height'
|      The `:width' and `:height' keywords are used for scaling the
|      image.  If only one of them is specified, the other one will be
|      calculated so as to preserve the aspect ratio.  If both are
|      specified, aspect ratio may not be preserved.
`----

But that new feature is only present in the current bzr trunk.  You
might want to have a look at the included `doc-view.el', which uses that
facility to zoom images if imagemagick support is present:
`doc-view-enlarge' and `doc-view-shrink'.

The git version of Gnus (and the version included in the emacs bzr
trunk) also use that feature in `shr.el' to render inline images with an
appropriate size in HTML mails.

Thanks for the information.  In the meantime, I tested Vladimir's 
patch, which also relies on ImageMagick support.   I couldn't test
this patch very far as 

  M-: (imagemagick-register-types) RET 

crashed my emacs (24.0.50.2).  Will update my emacs and try this again.
Would be a nice thing to have rescaling/slicing of images in org.

I've got the same problem and it seems like rebuilding the agenda buffer
makes the inline images disappear.
