Is there any way to (brute) force the placement of a figure at a specified location in a LaTex document and having all text wrap around it?

Question

I'm working on an assignment, and I've been working on this specific typographic issue on and off now for two'ish days. Having google'd a lot, read a lot, and tried a lot of the suggestions posted here, I've learned that I'm not the first person searching for an answer to this question, but I haven't managed solve it myself and make the assignment look like anything worth submitting.

What I'm looking for is preferably a way to assign a figure and a figure text to a certain set of pixels at the page and having them stay fixed in place no matter what else might be going on at the page.

What I have made so far looks like this:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{relsize}
\usepackage{physics}
\usepackage{setspace}
\usepackage{graphicx}
\usepackage{float}
\usepackage{wrapfig}
\usepackage{lipsum}
\usepackage[a4paper, margin={2cm,1.5cm}]{geometry}
\spacing{1.33}

% pictu{picture.png}{right/left}{size}{ref-label}{figure text}
\newcommand{\pictu}[5]{\begin{wrapfigure}{#2}{#350\textwidth}
\includegraphics[width=#350\textwidth]{#1}
\caption{\setstretch{1}\centering\label{#4}#5}
\end{wrapfigure}}

I have included an example of the current typography of a page produced by the code in the end of this novel.

To make the code look cleaner, I made a \newcommand, \pictu, which (to my knowledgde works exactly like just pasting the wrapfig environment each time - neither works ideally though). Feel free to question or correct the code. I'm not looking for fixes - I'm convinced that I'm not anywhere near the right track of a pretty solution. I won't hesitate to abandon this code for something that works.

I've often read that one should just let "LaTex do its thing" and place the figures, where they fit best with the rest of the text, but this has not worked for my case. That's why I initially began to deal with wrapfig.

What I need is to know, if there is a way to force images to remain fixed at specific pixels of the page, or if I have to resign and invest in a Microsoft Office license (I really do want this to work, but so far I'm incapable).

Sorry, for any possible mistakes or lack of knowledge or etiquette regarding my question - I'm new to both latex and to the forum. And if this question has already been answered, do let me know!

And thanks in advance!

Once you fix the unrelated errors so that you get some pdf output then if you are prepared to put in a small amount of handwork at each figure it is usually possible to control the white space around each figure, for example:

\documentclass[draft]{article}
\usepackage[utf8]{inputenc}
%\usepackage{amsmath}\usepackage{relsize}\usepackage{physics}
\usepackage{setspace}
\usepackage{graphicx}
%\usepackage{float}
\usepackage{wrapfig}
\usepackage{lipsum}
\usepackage[a4paper, margin={2cm,1.5cm}]{geometry}


% pictu{picture.png}[lines]{right/left}{size}{ref-label}{figure text}
\newcommand{\pictu}[6][]{\noindent\begin{wrapfigure}[#1]{#3}{#4\textwidth}
\includegraphics[width=#4\textwidth]{#2}
\caption{\label{#5}#6}
\end{wrapfigure}}
