bashgal is simple bash shell script that generates HTML thumbnail galleries using the "convert" and "jhead" command-line utilities. It requires no special server-side script to run to view image galleries because everything is pre-rendered.
Here are some key features of "bashgal":
· fixed-height thumbnails which fill the browser efficiently
· multiple image sizes which can be switched between by the user at any time
· css spriting of thumbnails to produce fewer server round trips and overall smaller data tranfer (see http://shapor.com/bashgal)
· locally previewable galleries by accessing images locally (e.g. file:///home/shapor/pics/blah/index.html)
· preloading of previous and next images using JavaScript. (This is *not* required and the gallery functions just fine without JavaScript).
· JPEG header EXIF data extraction
· auto-rotation of veritcal images
This combination of features makes a better user experience than pretty much all the big online photo hosts. All you need is a place to host your
plain html/jpeg files.
Usage:
bashgal [path]
Without specifying a path, bashgal works in the current directory. Just load the [path]/index.html in a browser see the output. [path] should contain a bunch of jpeg files. It does not work recursively (yet).
History
bashgal started as an alias in my .bashrc because I got sick of typing a command which looked a lot like this every time I would upload a new set of photos to my server:
$ for i in *.jpg; do convert -scale x100 $i t-$i; echo "" >>index.html; done
Even this simple one-liner gives you a gallery which is better than the majority of the on-line photo hosts. One of my pet-peeves is a tiny window surrounded by white in my huge browser window, requiring me to scroll.
