Directory structure

This toolkit requires your images to be organized in a specific manner.

A certain directory is the root:

uploads/images

Images that belong to certain entities (articles, users, etc.) are located in directories that correspond to those entities and their ids:

uploads/images/article/123
uploads/images/user/456

Every image should have an alphanumeric name (usually some kind of hash) and a proper extension:

uploads/images/article/123/acbd18db4cc2f85cedef654fccc4a4d8.jpg
uploads/images/user/456/37b51d194a7513e45b56f6524f2d51f2.png

Web Package

Getting images

Suppose the original image is available at this URL:

and you need it resized to 300x400 pixels. Simply add the desired dimensions to the name of the image as shown below:

The image will be resized proportionately and excess cropped. Not bad, right?

But what if only one of the dimensions is significant, and the other one is not? In this case, you need to set the non-significant dimension to zero:

or

Placeholder

The system can be configured to work with placeholders to serve when the image is not available. Placeholder file is usually named placeholder.png. There are two kinds of placeholder - general and entity-specific. General placeholder is placed into the root directory, entity-specific placeholder is placed into the entity directory:

http://example.com/uploads/images/placeholder.png
http://example.com/uploads/images/article/placeholder.png

With this configuration, article images have their own specific placeholder, while user images fall back to the general placeholder. Requesting a non-existent user image will return the general placeholder (http://domain.com/uploads/images/placeholder.png), while requesting a non-existent article image will return the entity-specific article placeholder (http://domain.com/uploads/images/article/placeholder.png).
