zsh-image-extension provides the image viewing capabilities to zsh. It allows previewing images listed on the command line and graphically selecting the images to append to it.

Image preview

You can preview the images listed in the command line in the terminal window by pressing ctrl+x ctrl+o (i.e. ctrl+x and then ctrl+o). Press any key dismiss. If there are too many images to display, any key other than 'q' will display the next image portion.

The preview function may be used as a regular command by running ils (image ls).

May not work with all the terminals. Confirmed to work with urxvt, xterm and the Linux tty.

It needs the w3mimgdisplay utility usually provided by w3m or w3m-img package.

The activation sequence may be customized by setting the IMAGE_EXTENSION_PREVIEW_KEY variable prior to loading this plugin.

Image selection

To graphically select images to append to the command line, press ctrl+x ctrl+o. A new window with the thumbnails will appear. Use arrow keys and/or hjkl to navigate, Enter to zoom in/out and 'm' to mark files to be added (a small asterisk/star should appear in the lower left corner).

If there is a path before the cursor, the files in that directory will be listed. The current directory is used otherwise.

Please refer to the sxiv documentation for more advanced usage.

The activation sequence may be customized by setting the IMAGE_EXTENSION_SELECTION_KEY variable prior to loading this plugin.

This method will not work if you do not have this plugin's Git repository downloaded. Use the method described in the next paragraph in that case or just download that repository.

Run make to download the sxiv source and compile it, and then source (i.e. add the source path/to/file line to your zshrc) the zsh-image-extension. You can provide your own config.h and recompile sxiv (by running make again).

If you have sxiv installed, you may omit the most of it and only source the zsh-image-extension file but I cannot guarantee your sxiv's compatilibity (the first compatible commit -- fb6e4bd).

• sxiv (automatically provided) for image selection
• w3m (w3m-img on Debian, Ubuntu, etc.) for image preview
• git and make for automated sxiv download and compilation

All images are selected every time

You are using an old sxiv version which does not support the mark command. Run make to compile the compatible version.

Image previews are too big/too small

It should be handled automatically but if it isn't, there is a config section on top of the image-preview.py script, so you can adjust it for your screen size. (the default was set on 1680x1050 and should autoscale unless in tty)

Image preview are not cleared properly

It happens under the composing window managers. Enable the legacy clearing method in the zsh-image-extension file or set the IMAGE_EXTENSION_CLEAR_FALLBACK variable to 1.

• a proper image clearing method working for tty and compositing window managers

To list and select images I've used the excellent sxiv image viewer written by Bert Muennich as it is great, small and hackable. ;)

Image previewing is handled by the w3mimgdisplay utility provided by w3m.
