Dependencies

• Drupal 6.x
• json functions
• curl extension
• PHP 5 (for exceptions and __construct niceties)
• bcmath functions for the stats page (everything is stored as bytes which could be a really big number when summed)

Install

• Add a folder to your modules directory called smush_it
• Put these files in it.
• Activate the module.

Features

• Will run on node create / update when new images are found

• Can run on cron (default: off)

  • You can set the number of images to be processed

• Can run on insert/update of a node (default: on)

  • If your insert/updates are timing out (or you plan on adding a pile of images to nodes) you will want to disable this
    • Note: if you disable this, you should enable the cron job

• Can run in testing mode for local development

  • When on, you point it at a web accessible file
  • This file will replace your files (the files will still be around in the .old form)

• Can smush individual images from the Files tab

• Can revert images from their smushed state (if the smushed file is messed up)

• Can set files to be ignored by the smush_it cron job (so they don't get messed up again)

• Added stats page (if bcmath is loaded)

  • Contains:
    • Original Image Size:
      • Original image size before being smushed
    • Bytes Saved:
      • Total bytes saved by smush.it (goes up to YB)
    • Smushed Size:
      • Total image size after being smushed (goes up to YB)
    • Images Smushed:
      • Total images processed by smush.it
    • Average Bytes Saved:
      • Average number of bytes saved per image (goes up to YB)
    • Images:
      • Images that have been uploaded
    • Images To Process:
      • Images left to be processed

Usage

• This module will copy your original image to a .old file.
• Then it asks smush.it if there is a smaller version of the file available
• Then it pulls down the smushed file if there is one
• It will then record the difference in size in the smush_it table
• The new image replaces the old one
  • the old one is still saved as x.old incase of a problem

Notes

• If the file is a gif, it could come back as a png (browsers generally don't care what kind of image it is)
  • If it does, the file will still be /path/to/file.gif but the mimetype in the file system will be changed to image/png
    • This means that files you have linked to on your site will not break

TODO

• redirect back to the same page you came from after [ignore|smush|revert] action is taken
