ImageMagick and GD are software libraries that ought to be present on a hosting server to enable images to appear on a certain site. They enable you to perform a variety of tasks with the images - create, flip, resize, change colors, and so on. These things can easily be performed online and in real time, so if you add a static image, for example, the libraries make it possible for a thumbnail to show up on the website or for the image to be resized automatically based on the device and resolution which the website visitor is using. Both ImageMagick and GD may be employed with many web programming languages including PHP, Perl and Python, so you do not need to stick to just one language to develop your website. They work with over 100 formats, which includes the most frequently used ones - JPEG, GIF, TIFF, PNG, and so forth.
