The problem that you are going to have is that a .jpg file is a raster type file, similar to bitmap files; an igs file is a vector type file. I talked with our tech writers and cad administrator and they know of any way to convert the jpg to igs.
If you have to have this logo in the drawing, you may need to recreate the logo in a format that Pro/E will recognize. To the best of my knowledge, there is no way to put a .jpg file format onto a Pro/E drawing.
Sorry to be the bearer of bad news but I am open to new ideas and solutions.
