There are many tools, libraries and widely used design software for processing images, with more or less flexibility, but doing it in Grasshopper opens the doors to brand new workflows. One can think of processing images using geometric algorithms, a set of tools that is not easily accessible in most image processing environments. Combined with the new Make2D component from Rhino 6, the possibilities are limitless. Another simple but powerful application is the creation and application of parametric textures over 3d models. This is particularly interesting for designing products with personalized prints (for instance custom t-shirts or mugs).
