26 | ;; This package create two new modes: thumbs-mode and thumbs-view-image-mode. |
27 | ;; It is used for basic browsing and viewing of images from within Emacs. | |
28 | ;; Minimal image manipulation functions are also available via external | |
da6062e6 | 29 | ;; programs. If you want to do more complex tasks like categorize and tag |
a6009bd1 | 30 | ;; your images, use image-dired.el |
ab6d47ea RS |
31 | ;; |
32 | ;; The 'convert' program from 'ImageMagick' | |
33 | ;; [URL:http://www.imagemagick.org/] is required. | |

41 | ;; CHANGELOG |
42 | ;; | |
43 | ;; This is version 2.0 | |
44 | ;; | |
45 | ;; USAGE | |
46 | ;; | |
47 | ;; Type M-x thumbs RET DIR RET to view the directory DIR in Thumbs mode. | |
48 | ;; That should be a directory containing image files. | |
49 | ;; from dired, C-t m enter in thumbs-mode with all marked files | |
50 | ;; C-t a enter in thumbs-mode with all files in current-directory | |
dd2a3d13 NR |
51 | ;; In thumbs-mode, pressing <return> on a image will bring you in image view |
52 | ;; mode for that image. C-h m will give you a list of available keybinding. | |
