ImageMagick
ImageMagick is a cross-platform application used to view, edit, and convert images from a large variety of imaging formats. You can do a number of tasks using the tools provided within the software. By adding text or shapes, you can artistically change the appearance of photographs.
An image can have borders or frames added to it, as well as a number of additional effects including image blur or sharpening. Additionally, you may use a collection of photographs to make GIF animation sequences.
