Easy PHP Thumbnail Class can be used to manipulate images and generate thumbnails. It can load images from files and generate thumbnails that can be saved to files or be generated as the current script output. The class can also perform other image manipulation functions such as adding shadows, clipping rounded corners, filters, bilineair image deformations, and more. Over 45 image manipulation functions are available.
PHPGallue is a multi-user, server-oriented image management system with a Web frontend. PHPGallue is suited for photographers to organize and publish their work. It allows the user to mark images, groups, categories, films, and series as private or as only visible to registered users. It is designed especially for large numbers of images. The Web frontend and backend libraries are completely separated, so it is easy to integrate PHPGallue as a management system into existing Web applications.
Asido is an image processing solution for programs written in PHP 4 or PHP 5. It features "pluggable" drivers (adapters) for virtually any environment: either GD2, ImageMagick via shell, ImageMagick via the PHP extension, Magick Wand, or others. It offers the following functionality: resize images, watermark images, rotate imatgs, copy images, crop images, grayscale images, convert images, etc.
Instant Picture Creator is a wrapper to produce images on demand for Web sites. It has filter management, and it's possible to add new filters. It can cache filtered images, works independently (no backend is needed), and is easy to integrate with existing Web sites. It includes two basic filters for resizing images and manipulating colour palettes. Currently it supports PNG, GIF, and JPEG.
Shref Image in DB is a PHP class that can store and retrieve binary files in a MySQL database table. The class can read the data from one file, convert the data to an ASCII representation, and store it in a given a given record of a MySQL table field. The class can also do the opposite. It retrieves the data from a given MySQL database table field record, decodes it, and outputs the decoded data.
JPEG Fit is a PHP class that can be used to optimize images to fit within a given file size limit. It takes a picture in any format supported by the GD library and generates a JPEG picture with the maximum quality factor that makes the picture file size not exceed a given limit. This class is similar to the JPEG Reducer class. It uses the binary search algorithm to reach the ideal quality factor in the smallest number of iterations. The class stops searching when a given number of limit iterations is reached, or when the quality factor difference between the ideal and the found values is less than the configured precision value.
Eyefi I2 is an API for the abstraction of all common image transformations (thumbnailing, scaling, borders, etc.) into an XML file. Through a simple PHP API, images can be loaded through such a transformation to generate and cache a modified image. By stacking the image operations, very complex transformations can be accomplished, incorporating source images, generated text, image overlays, and more.
