A major issue is that you assign copyright to many publications, meaning that it's infringement to reuse an image in another publication. The rest of the problem is basically one of passing off already published results as new ones. Of course, because reviews take for fucking ever and can be hit by unexpected obstacles, you will not know the publication order of your articles in advance, so properly referencing parts of the work as already published while it's in pre-pub limbo is difficult. Arxiv helps a lot there, but there are still many traps.
