Download the latest package manually or better use the composer

composer require rostenkowski/resize


The best way is to use the built-in Nette DI container extension in application configuration, usually located in app/config.neon. You can place the imageStore part of the configuration to your local configuration file.

    resize: Rostenkowski\Resize\Extension

    storageDir: %baseDir%/data/images
    cacheDir:   %baseDir%/www/images
    basePath:   /images/

Manual configuration

If you aren't using the the DI extension the image macros should be registered to the Latte engine as described in the docs:

            - Rostenkowski\Resize\Macro\ImageMacro::install

The storage can be created manually in presenter or registered as service this way:

    - images: Rostenkowski\ImageStore\ImageStorage("%baseDir%/data/images", "%baseDir%/www/images", "/images/")


  • PHP Suggested 5.6, Minimal 5.5
  • Nette Suggested 2.3, Minimal 2.2

The library is tested against PHP 5.5, 5.6 and 7.0 and Nette 2.3 but it should be compatible with previous stable Nette 2.2 and the latest Nette 2.4-dev as well.

// check that an image already exists in the storage
$storage->contains(Meta $meta);

// fetch original
$storage->original(Meta $meta);

// rotate image
$storage->rotate(Meta $meta, 90); // Meta

// downloaded requested thumbnail
$storage->download(Request $request); // Nette\Application\Responses\FileResponse

// fetch requested thumbnail
$storage->fetch(Request $request);

// link requested thumbnail
$storage->link(Request $request);

// output requested thumbnail to stdout
$storage->send(Request $request);

Technical overview

  • The images are stored in regular files in the given directory.
  • The files are organized in a directory tree with maximum of 256² directories in two level structure so with ~1K files in a directory the storage is able to store ~6.5M of images without performance impact.
  • The directory tree is well balanced thanks to image hashes used for the directory path creation.
  • The storage stores only one file even if the same image is stored multiple times.
  • The image thumbnails are created on demand and cached in the cache directory.
