phpThumb() - The PHP thumbnail generator

phpThumb() uses the GD library to create thumbnails from images (JPEG, PNG, GIF, BMP, etc) on the fly. The output size is configurable (can be larger or smaller than the source), and the source may be the entire image or only a portion of the original image. True color and resampling is used if GD v2.0 is available, otherwise paletted-color and nearest-neighbour resizing is used.
