;; This package create two new mode: thumbs-mode and

|
|
;; from within emacs. Minimal image manipulation functions are also
|
|
;; available via external programs.
|
|
;;
|
|
;; The 'convert' program from 'ImageMagick'
|
|
;; [URL:http://www.imagemagick.org/] is required.

|
|
;; USAGE
|
|
;;
|
|
;; Type M-x thumbs RET DIR RET to view the directory DIR in Thumbs mode.
|
|
;; That should be a directory containing image files.
|
|
;; from dired, C-t m enter in thumbs-mode with all marked files
|
|
;; C-t a enter in thumbs-mode with all files in current-directory
|
|
;; In thumbs-mode, pressing <return> on a image will bring you in image view mode
|
|
;; for that image. C-h m will give you a list of available keybinding.
