Linking images and SVG files can be especially helpful when working simultaneously with Photoshop, Illustrator or Sketch. All images embedded in your wireframe will be automatically updated whenever files are modified.

Furthermore, with Justinmind you can import, embed or link any SVG and other Vector files. You can also change their color, and scale them without losing quality.
