If you would like to have dynamic images on your internet site, the server in which you host it must have the proper software for that. As opposed to using static images with a fixed size, you may have thumbnails and automatically resized images in accordance with the device a website visitor uses or you may even flip and invert images through a script app. All these things are feasible with ImageMagick and GD library - 2 pieces of software that can be set up on a server and that work with a large amount of frequently used scripting languages like: Perl, Python and PHP. In this way, you may use images with any web-based application that you'd like, no matter what language it was created with - a custom-made Perl script or a PHP one. The 2 libraries will permit you to work with over one hundred different image formats like GIF, PNG, TIFF, JPEG, and so forth.
