ImageMagick and GD are software libraries that ought to be present on a server for images to show up on a particular website. They permit you to perform different tasks with the images - create, flip, resize, change colors, and so forth. These things could be carried out online and in real time, so if you add a static image, for example, the libraries make it possible for a thumbnail to appear on the website or for the image to be resized automatically depending upon the device and resolution which the site visitor is using. Both ImageMagick and GD may be employed with a lot of web programming languages such as PHP, Perl and Python, so you do not have to stick to a single language to develop your internet site. They work with more than a hundred formats, including the most widely used ones - JPEG, GIF, TIFF, PNG, etc.
