One of my favorite recent discoveries in emacs is
M-x image-dired. Point it
toward a directory with photos, and it creates a buffer full of thumbnails for
you. That by itself is useful to me — I've not been happy with any other
software I've tried for just looking at the pictures on my camera's SD card and
copying off the ones I want. Everything has been either too heavy or too old.
It wouldn't be useful to me except for emacs's multi-tty feature, which lets me
open a graphical X frame to an emacs session running in GNU Screen. I never
used graphical emacs frames before because doing so meant not being able to
keep the session persistent in Screen, which was much more important to me. But now I can have both.
Often I also need to rotate the photos when I copy them from my camera. You can do
this by pressing
R in the thumbnail buffer. At first it didn't work. A
little documentation reading revealed that emacs calls to an external program
to do the rotation, called "jpegtran". After installing that, I can rotate the
pictures. This program might be packaged as part of "libjpeg-progs" in your
In addition to rotation, photos can be copied, moved and deleted by using usual
dired keybindings. There is also support for adding comments.
So, basic photo management — yet another common task I can do inside of emacs.
