If you would like to have dynamic images on your website, the web server in which you host it should have the suitable software for this. As opposed to using static images with a fixed size, you may have thumbnails and automatically resized images based on the device a visitor uses or you can even flip and invert images through a script app. All these things are possible through ImageMagick and GD library - 2 pieces of software that may be set up on a web server and which work with a great number of frequently used scripting languages such as: Perl, Python and PHP. Thus, you may use images with any web-based application that you would like, no matter what language it was developed with - a custom-made Perl script or a PHP one. The two libraries will allow you to work with over 100 different image formats such as GIF, PNG, TIFF, JPEG, etcetera.
