ImageMagick and GD are software libraries that ought to be present on a web server in order for images to appear on a specific website. They permit you to execute different tasks with the images - create, flip, resize, change colors, and so on. These things could be performed online and in real time, so if you include a static image, for example, the libraries make it possible for a thumbnail to show up on the internet site or for the image to be resized automatically based on the device and resolution which the visitor is using. Both ImageMagick and GD may be used with lots of web programming languages such as PHP, Perl and Python, so you do not need to stick to only one language to create your internet site. They work with more than a hundred formats, which includes the most popular ones - JPEG, GIF, TIFF, PNG, and so forth.
