Thumbnail and Watermark is a class that can process an image on the fly by either generating a thumbnail or applying a watermark. The processed image can be displayed in a page, saved to a file, or returned to a variable. If version 2 of the GD library is available, the class can manipulate the images in true color. It supports multiple watermark positions, and auto-fitting that adjusts dimensions so that the resized image aspect is not distorted. Both JPEG and PNG are supported, but the watermark image can only be in PNG format as it needs to be transparent.

Multi-thread Simulation is a PHP class that can emulate the execution of program threads using separate HTTP requests to the same script. It establishes an HTTP connection to the same Web server to execute the same PHP script. It sends a request that passes the name a function to execute and an argument to be passed to that function. The requested script executes some code that detects the thread execution request and calls the specified function. When the thread request script ends, the return values of the called function are returned as a serialized string.
