# Chapter Cover pages with image and chapter numbering

I am currently writing my thesis and would like to edit the template I am using MastersDoctoralThesis. Precisely, I would like to have every chapter being introduced with 4 pages (#1: page displaying the number of the chapter in large; #2: full page image; #3: the abstract or a quotation relating to the chapter; #4: title and number of the chapter with a short note on the authors at the bottom). Despite looking for this for a couple of days now on various platforms this seems to be rather hard to accomplish. Hence, I would be more than grateful to receive help on this as it defnitely exceeds my personal capabilities.

This is not really an answer but I think that it is too long for a comment.

First thank you for providing lots of code but I wasn't prepared to go chasing around after your MastersDoctoralThesis template. I also didn't want to clutter up my OS with lots of ancillary files such as your chapter MWE and the chapter definition (.cls) file and merged then all into a single \documentclass{book} file and made appropriate adjustments to comment out code that that was only supported by the class you were using.

The end result was that the chapter head looks like the default. I must admit that I don't follow your \@makechapterhead code but I'm too ancient to keep up with all the new coding styles.
The \chapter macro takes two arguments \chapter[<toc entry>]{<document title>}. I think that you might be after a macro \mychapter[<toc entry>]{<document title>}{<graphic>}{<abstract>}{<authors>} where the chapter number is printed on the first page, then a \clearpage and <graphic> is printed followed by a \clearpage followed by <abstract> followed by \clearpage with a typical chapter number and title and at the bottom of the page <authors>.
