If you would like to have dynamic images on your website, the server where you host it must have the suitable software for this. Instead of using static images with a fixed size, you could have thumbnails and automatically resized images based on the device a site visitor uses or you could even flip and invert images via a script application. All these things are doable through ImageMagick and GD library - 2 pieces of software which could be set up on a hosting server and that work with a wide range of popular scripting languages including: Perl, Python and PHP. This way, you could use images with any web-based application you want, irrespective of the language it was developed with - a custom-made Perl script or a PHP one. The 2 libraries shall allow you to work with over 100 different image formats such as GIF, PNG, TIFF, JPEG, and so forth.
