Zebra - display images in urxvt

The Zebra script.

Needs: ‘w3m-img’ (w3mimgdisplay) and supported terminal like xterm or urxvt. And probably more.

Todo: ↓

• maybe: add rename image (should also rename array member?).
• done: add touch to update file date.
• done: add specific key (r) to reset view.
• done: cycle wallpaper setter modes (–set-centered –set-scaled –set-tiled –set-zoom –set-zoom-fill).
• maybe: thumbnail view (also –thumbnail to start in thumb view)
• done: simple slideshow
• done: toggle 1:1 view
• done: –quit some.png (show first and quit)
• no, use zsh globing*(om): sort files (array) by date
• done: goto is internal command only.
• done: open in gimp.
• maybe: pngcrush, pngquant
• maybe: add thunar-compatible emblem

Known bugs: ↓

• zebraview sometimes doesn’t show alpha as transparent (uses white instead), limited to urxvt (always ok in xterm).
• image disappears when urxvt is not in focus (again ok in xterm).

Acknowledgments ↓

Zebra is based around the code found here.

Überzug, complicated alternative ↓
