Many of our supported website applications (eg: Coppermine Photo Gallery, WordPress blog) use ImageMagick to display, convert and edit image (GIF/JPEG) files

ImageMagick can read over one hundred image file formats and processes them via the command-line. It does not have a GUI interface to edit images, so it is not like Photoshop; but has several command-line parameters to manipulate the images.

Most of the time you don't have to worry about ImageMagick as it will just work, however if you are a developer looking to integrate it into your code, you will need to refer to the documentation for the command-line options.
