How to imbed jpeg images on a part

We created a nice panel with all our sponsor logos on it.

The images are imported jpeg files for each logo.

The issue we are having is when checking in this panel into Windchill, the images do not seem to come along so when other team members open the part on their computers, there are no images on the panel, only blank outlines where the jpeg files were inserted.

Does anyone know how to get this to work so anyone can open the robot model and see the jpeg images on the panel?

Thanks so much
