Mercedesshop does host images up to 64k in size. So your image will be fine. However, it does not show up in preview mode. You just have to take a leap of faith and submit the post. If something goes wrong, you can always delete the post later by pressing the edit button. When the edit screen comes up you check the delete box and then press the delete button.
