If you would want to have dynamic images on your site, the web server where you host it ought to have the suitable 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 can even flip and invert images using a script app. All of these things are doable with ImageMagick and GD library - two pieces of software which may be set up on a server and that work with a large amount of frequently used scripting languages such as: Perl, Python and PHP. Thus, you can use images with any web-based app you want, regardless what language it was developed with - a custom-made Perl script or a PHP one. The 2 libraries will allow you to work with over a hundred different image formats including GIF, PNG, TIFF, JPEG, and so on.
