The importing of images for use and processing with the STEPCRAFT CNC is purely dependent on the CAM software that you are using.  For example, Vectric Cut 2D and V Carve both allow the importing of images in the following formats: .bmp, .jpg, .gif, .tif, .tiff, .png and .jpeg. You can not import native files from Pagemaker, Word, etc., only common bitmap formats.
If you have an image in another format or from another program, you can always import them into a graphics program like GIMP or Photoshop and then output them from there.
