How can I insert the figure inside text without caption and label in LaTeX?

Question

I would like to have something like this:

Answer 1

Like this?

\documentclass{article}
\usepackage{lipsum}
\usepackage{wrapfig}
\usepackage{graphicx}

\begin{document}

\begin{wrapfigure}[5]{l}{3cm}
\includegraphics[width=2.5cm]{example-image-a}
\end{wrapfigure}
\lipsum[1]

\begin{wrapfigure}[6]{l}{3cm}
\includegraphics[width=2.5cm]{example-image-b}
\end{wrapfigure}
\lipsum[1]
\end{document}

Answer 2

The question shows a misunderstanding of what \includegraphics{} does and how it should be used, assuming that it has to be used always as part of a figure environment. This is not the case.

You can write \includegraphics{foo} at any point of your text, even in the middle of a paragraph, and the graphic will be inserted at that point, as if it was any other char (only that, probably, bigger).

In particular you can use an external image even as argument of \item[], which provides another possible answer for your question:

\documentclass{article}
\usepackage{graphicx}
\usepackage{lipsum}
\def\Duck{\includegraphics[width=3ex]{duck}}
\def\Turtle{\includegraphics[width=4ex]{turtle}}

\begin{document}
\lipsum[1]

\begin{itemize}
\item[\Duck] \lipsum[2]
\item[\Turtle] \lipsum[3]
\end{itemize}
\end{document}

Answer 3

If it must not float, the simplest is to write in your preamble

\input{insbox}

(it's a set of plain tex macros) and use in the body of your document, before each paragraph,

\InsertBoxL{n}{\includegraphics{your_figure}}

where n is the number of lines that must remain full length before the graphics file is inserted — typically in your case, n=0. An optional argument allows for a correction (in number of supplementary lines to be indented).

Demo:

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx} 

\input{insbox}

\begin{document}

\InsertBoxL{2}{\includegraphics[scale=0.25]{sendak.png}}Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec varius dapibus metus eget ultrices. Nulla sagittis mauris rutrum, blandit augue eget, laoreet augue. Phasellus enim odio, sagittis in mi sed, fringilla mollis odio. Phasellus quis purus ultricies, tempor purus at, tempus quam. Donec ultricies, ligula ac pretium porttitor, nibh nunc. Integer eros nibh, cursus at est sed, volutpat tristique justo. Donec ornare facilisis lorem, id feugiat elit pellentesque at. Nulla odio mauris, luctus sed faucibus id, dignissim dictum velit. Morbi vehicula velit at massa tristique rhoncus.%

\InsertBoxL{0}{\includegraphics[scale=0.25]{sendak.png}}%
Phasellus quis purus ultricies, tempor purus at, tempus quam. Donec ultricies, ligula ac pretium porttitor, nibh nunc.Integer eros nibh, cursus at est sed, volutpat tristique justo. Donec ornare facilisis lorem, id feugiat elit pellentesque at. Nulla odio mauris, luctus sed faucibus id, dignissim dictum velit. Morbi vehicula velit at massa tristique rhoncus.

\end{document}
