Installation of GD on Linux CentOS4.3

The GD Graphics Library is a library by Thomas Boutell and others for dynamically manipulating images. Its native programming language is ANSI C, but it has interfaces for many other programming languages. It can create GIFs, JPEGs, PNGs, and WBMPs.GD can create images composed of lines, arcs, text (using program-selected fonts), other images, and multiple colors. Version 2.0 adds support for truecolor images, alpha channels, resampling (for smooth resizing of truecolor images), and many other features.GD supports numerous programming languages including C, PHP, Perl, O'Caml, Tcl, Lua, Pascal, GNU Octave, REXX, and Ruby.GD is extensively used with PHP, where a modified version supporting additional features is included by default as of PHP 4.3 and was an option before that.
