If you would want to have dynamic images on your internet site, the server in which you host it ought to have the correct software for this. As an alternative to using static images with a fixed size, you can have thumbnails and automatically resized images based on the device a site visitor uses or you may even flip and invert images through a script app. All these things are doable through ImageMagick and GD library - two pieces of software which could be set up on a hosting server and that work with a wide range of popular scripting languages such as: Perl, Python and PHP. This way, you could use images with any web-based application you'd like, regardless what language it was designed with - a custom-made Perl script or a PHP one. The two libraries will permit you to work with more than a hundred different image formats including GIF, PNG, TIFF, JPEG, and so on.
