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.
as_snipercaptcha is a PHP class that can be used to implement CAPTCHA validation using colored boxes that the user must click and which are validated using AJAX requests. It renders a grid of boxes on which only one box is colored differently to indicate the user must click it. The class sends an AJAX request to the server, passing the coordinates of the user clicks until a given number of clicks correctly point to the colored boxes.
Micro Login System is a simple PHP-based user login system that stores user registration information in a flat file instead of a MySQL database. It is easy to install and change the design via CSS. The package contains login, logout, and registration forms. An integration example is included.
awfDialog Wizard can be used to generate a wizard-like Web based user interface using AJAX to avoid reloading the page when advancing to a new step. It features modal forms dialogs that cannot be closed, or non-modal with an exit button. It displays included or custom icons, which may have standard 32x32 or 20x20 sizes. A Wizard display mode causes the form content region to render in two side-by-side panes. There are AJAX wizard buttons to go to the previous and next pages or cancel. You can use the built-in Help display, or override it with your own AJAX methods. The forms have configurable gradient title bar colors. The user interface elements have unique ID values to allow customization of presentation details via CSS.
