我无法访问我的图像文件，因此我只想编译文本。我认为使用draft模式可以解决这个问题，但我仍然收到“无法找到图像文件”错误。
我怎样才能编译而不必复制一些随机图片做有。
这是我的标题
\newcommand{\rootFolder}{/home/pa06r/pa06r-thesis}
\documentclass{\rootFolder/latex_templates/tex/latex/ecsdocs/ecsthesis}
\graphicspath{{\rootFolder/images/}} % Location of your graphics files
\usepackage[demo]{graphicx} %Use for graphics
\usepackage{subfigure} %Use for side-by-side figures
\usepackage{float} % Use for floating figuress
\usepackage[round]{natbib} % Use Natbib style for the refs.
\usepackage{multirow} %Use for multirow tables
\usepackage{rotating} %Use for rotating tables
\usepackage{colortbl} %Use for coloring table backgrounds
\usepackage{algorithmic} %Use for algorithms
\usepackage{algorithm} %Use for algorithm labels
\usepackage{ulem} %Use for strikethroughs
\usepackage{listings} %Use for Pseudocode
\usepackage{color} %package listings needs this
\usepackage{textcomp} %Used for tilde character
\hypersetup{colorlinks=true} %Set to false for black/white printing
\usepackage{lscape} %For rotating pages with long images
根据 Joseph Wrights 的要求，这是最简单的示例。我创建了一个.tex文件，其中包含以下内容
\RequirePackage[demo]{graphicx}
\documentclass{article}
\begin{document}
\includegraphics{'img.jpg'}
\end{document}

demo套餐选择是graphicx你的朋友
\usepackage[demo]{graphicx}
将在真实图像的位置插入一个方形黑色“斑点”，并且不会搜索它们。（该draft选项不包括图像，但会找出它们的大小，这仍然需要文件。）
该demo选项完全忽略文件。因此，所有“blob”的大小都相同，除非有明确的高度或宽度作为参数给出\includegraphics。
在加载类（然后可能会加载graphic(s|x)）之前如何执行此操作的简短演示：
\RequirePackage[demo]{graphicx}
\documentclass{article}
\begin{document}
\includegraphics{whatever}
\end{document}
