In ThemeDesigner, there should be a "no-split" option. If you uncheck it, the median should reappear. As for placing the seem between the images in the middle, that would require that one of the images be cropped. You would either need to remove from the left/right of the left image or from the top/bottom of the right image. Let me know which you want to do as well as where you want to remove stuff from. For example, if we remove the top/bottom from the right image, do we remove an equal amount from both or remove everything from the top?

The issue regarding to the height just depends on the dimensions of the user's screen. There is no way to get it to fit perfectly for everyone. What you can do it check the "tile" option which should repeat the image vertically so that there isn't any empty background space.
