Greetings,

I discovered this mode through a blog post from Sacha:

<https://sachachua.com/blog/2025/01/using-image-dired-to-browse-the-latest-screenshots-from-multiple-directories/>

And I really liked it.

Though, I felt that it was missing something:

Some keybinds for navigation besides C-n and C-p, like those found in
other read-only modes, such as dired-mode.

This patch binds the following keys in `image-dired-thumbnail-mode-map':

- "f" :: `image-dired-forward-image'
- "b" :: `image-dired-backward-image'
- "n" :: `image-dired-next-line'
- "p" :: `image-dired-previous-line'
- "a" :: `image-dired-move-beginning-of-line'
- "e" :: `image-dired-move-end-of-line'

These keys are currently unused in the mode.

Regards,
