Hi, Read up on the image manipulation functions of PHP at http://www.php.net/manual/en/ref.image.php
You will need to install the GD library if it's not already installed and once you do you will have access to all the functions described, including the ImageCopyResized function. To read the image from disk, you will probably have to use ImageCreateFromGif or ImageCreateFromJpeg and to create the destination image you will need to use CreateImage. You can then save the resulting thumbnail using ImageGif, ImageJpeg or anything you like. Just as a side note, you should probably use ImageCopyResampled which uses interpolation to resize the image, thus creating a thumbnail of much better quality. HTH Olivier PS: to get the image's height and width, use ImagesY and ImagesX respectively, once you have opened/created the image.
