Well, you asked the question. I answered it. In the future, I will keep it short. Either yes or no. Back to the topic at hand. It seems that the upload through Ninja does upload the images. However, once online, I have to go into the listing and save/update it for the images to show up as part of the gallery. Perhaps you can forward this to the powers that be so they can look into this.
Cheers,
Michael
