How to structure the Introduction of my Master's thesis? My question is not about the structure of an entire thesis, but just about the Introduction chapter. At the moment, it consists of the following sections:


Objective [where I briefly introduce the aim of my thesis]
Area of Research [where my thesis collocates in a more general pipeline]
Conclusion [where I very briefly summarize the content of each chapter].


It's very short (I'm trying to keep the complete thesis below ~50 pages), but there is more or less everything I wanted to say.

My supervisor suggested me to:


Expand it by adding more details, which is fine I can do it
Remove the sections in order to have just one big chunk of text and remove eventual images because the introduction should not contain any.


I disagree on the second point. Since I'm introducing different stuff, it's nice to be able to quickly understand what I'm talking about. Second, I never read that you should not put images or tables in the Introduction. So my questions are: (1) should I remove the Sections? and (2) should I remove the only image I have in the Introduction (it's more of a diagram that I describe in the main text)?



P.S. My supervisor does not work in academia and I'm not sure how many theses he has supervised. Moreover, my Department does not have any sort of guidelines for writing a thesis.

The introduction needs to answer three questions. WHY, WHAT &amp; HOW. 

Declare why the problem needs solving, what the problem is and what a solution will look like, and how you have intended to go about the business of getting from the former to the latter. In addition to this, it can be relevant to quote specific earlier research that you will be building your thesis upon. Maybe a reaction path, a lemma, whatever depending on which field it of course is.
