Force use of ImageMagick image library

Forces WordPress to use ImageMagick instead of the PHP GD image library. This allows EXIF and IPTC data to be retained – for example, those containing GEO data and copyright information – but can lead to slightly larger file sizes.

This plugin only instructs WordPress to use the ImageMagick library. It doesn’t change how (or when) WordPress generates images, and it doesn’t provide any additional functionality for creating or resizing images.
