PHP Image Gallery Script with multi-uploading, cropping, rotating and sorting features.

This script has been developed for multiple image uploads. It can be used not only for image gallery but also for multi-image upload for many different types of projects.

Images can be cropped, rotated before uploading. It can be sorted by dragging with the mouse on computers or by finger dragging on mobile devices, and information can be added for each picture.

FileAPI javascript tools are used for client side cropping, rotating and uploading images 
(https://github.com/mailru/FileAPI)

Uploaded images can be reordered later, new images can be added between them.

After installation, a picture table and a simple gallery table associated with this table are also created in the database.

In order to manage the created image gallery, simple page templates have been prepared.

In order to be easy to integrate into projects, a simple design has been made using bootstrap.

When it is installed, this script automatically creates a gallery as seen in the demonstration in the project directory. There are 4 pages on the project directory of this gallery. These pages are prepared as templates with a simple design for convenience to developers.

mi-uploader.php : create and edit gallery, upload and edit images for admin or authorized users
gallery-man.php : gallery management for admin or authorized users
gallery-list.php: list of image galleries for all users
gallery-view.php: view images of gallery for all users

You can use these pages by appropriately incorporating them into your project and improving their designs.

It is prepared as a template available to develop for different projects.

The codes are written as clearly and comprehensibly as possible. Necessary explanations have been added to the methods. Error logging and debug mode have been added to make it easier to find errors during the development phase.

                /thumb_c
            /xml            : xml files of image informations. It was created to reduce database queries. Used in gallery-view.php file.
        
        When the image is uploaded, first full size (not original size, maximum dimensions specified in the installation), thumbnail and slide images are created in the tmp directory. 
        After the gallery is saved, the gallery id is taken and a new folder with this name is created in img directory and the images are moved here.
        For example, when the file named abcdef123456789.jpg is uploaded, it is moved to the tmp directory.
        Let's say gallery info is inserted to database with 128 id. After that, the file is moved to the img/128/128-abcdef123456789.jpg folder.
