to handle images properly, they need to be placed in the correct place when passing an image to something that would display it, the image object has 2 parameters

image:

name: the_filename_of_the_image
global: [somevalue]

the value of global determines where the image is located it can have one of the following values

• global: image resides in the main projects-assets assets/images/global/
• project: image resides in the sub projects-assets assets/images/global/
• collection: image resides in the sub-projects assets assets/images/collections/[collectionName]/
• local: image resides in the sub-projects assets if it is a post it is in assets/images/posts/YYYY-MM-DD-post-title if it is a page part of a collection its location is assets/images/collections/[collectionName]/pageTitle/

if global is false or not set, it defaults to local. if global is set to true, it defaults to global.

each corresponding assets/images/ directory should also have a corresponding assets/images-original/ directory.

I'm using the default imagemagick stuff in ubuntu and standard gnu find. Other than that there is no dependencies for this little image processing script. In case you don't have it already

sudo apt-get install image-magick

That should provide the convert binary.

When you add new images you should run the minifyimages.sh script. The script will take all the images in the ../assets/images-original/ folder, minify them and put them in the ../assets/images/ folder if they don't already exist. It will also create the required subdirectories as needed. This could possibly be further automated with some git hooks but that is a bit of a pain.

This script also generates the images at different resolutions (a normal resized one for use in articles, and one that is resized and cropped to a height of 600px high for use in index pages), however the images are not guaranteed to be that lower resolution! If the resized image has a larger filesize than one resized at a larger size, the script will instead symlink to that smaller file which has a larger resolution.
