Image Resizer

Plugin Description:

This plugins let's you dynamically generate resized images from your uploads folder. It supports resizing by width, height, to fit in dimensions and fill in dimensions. It allows you to define allowed resolutions and quality of the generated images.It also automatically caches, resized images.

How to use:

• go into GS admin panel and select "Configure Image Resizer" from right sidebar
• enter resolutions that you want to use to resize image by height width, crop to fit or fill, separate them with commas
• in your template use image_resizer_src($mode, $resolution, $img) function to generate url for image
• Function parameters:
  • mode - allowed values are "height", "width", "fill" and "fit" it indicates how to resize image
  • resolution - one of definied values from configuration
  • img- path to image from GS data/uploads folder, allowed formats are:
    /data/uploads/img.jpg (root relative)
    http://example.com/data/uploads/img.jpg

If you want you can call resizing script directly, for example:
http://yoursite.com/plugins/ImgResizer/img/?by=height&resolution=1000&img=/data/uploads/items/sample.jpg

Some tips:

- to enable debugging mode, enable debug mode in GS by setting GSDEBUG to true in gsconfig.php file, all resizing script errors will be generated as images with some debug details
- when requested resolution is not on allowed list, it will return error if debug mode is on, or 404 page when debug mode is off
- if you requested resolution bigger than source image is it will return original image
