How to Directly Import Better Example Images for MWEs

Question

For the purpose of asking questions on this site related to images, I know that I can directly call in a basic non-descriptive image in the following manner:

\documentclass{article}
\usepackage{graphicx}

\begin{document}
\includegraphics[width=2cm]{example-image}\\
%\fbox{\includegraphics[trim=1 150 0 0,scale=0.1]{tiger}}
\end{document}

which produces

However, in some instances, an actual picture such as

would be more desirable.

I know that the above framed tiger can be produced with the command

\fbox{\includegraphics[trim=1 150 0 0,scale=0.1]{tiger}}

But it seems that this tiger image cannot be called in by the package graphicx.

Is the tiger image, as well as perhaps others like it, available for use directly by calling in some package? I suppose I can save this image which so often appears on this site to my computer and call it in that way, but then, someone who is going to answer the question I post will not be able to run my MWE without error.

QUESTION: What is the simplest way to incorporate the Latex tiger (and similar-type images) into a MWE for the purpose of asking a question on this site?

Thank you.

Answer 1

The tiger is a ghostscript test eps file not from the latex distribution and isn't in the default input tree.

There are a few images that are and make a change from example-image, for example \includegraphics{pink_marble} or \includegraphics{mill}. The last one is from context but latex will find it.

A full list of png files in texlive input tree is

 for i in $(grep '\.png' $(kpsewhich --all ls-R) | sed -e 's/.*://' | sort | uniq ); do kpsewhich $i; done

which shows up the following, obviously you could do similar for jpg or eps.

Answer 2

What is contained within an image is not something that should influence the way you handle the solution. You can definitely phrase the question and use an example image from mwe. That's the beauty of what mwe provides (from its documentation:

Once installed in the correct directory in the TEXMF tree they will be available to all documents. This way a user can compile any MWE given to him by another person which uses these image files without requiring code replacements or sharing images.

If you think the images are bland and need more colour, then use a page from example-image-a4-numbered or example-image-letter-numbered:

\includegraphics[page=10]{example-image-letter-numbered]

There's also example-grid-100x100pt and example-grid-100x100bp:

If you want to include a "sample document" (looking for more text), there's example-image-letter and example-image-letter-landscape (and other sizes, like a3, a4 and a5).

In my opinion, the mwe package elements are probably one of the most-used but least-mentioned elements (on this site), since you don't have to \usepackage{mwe} in order to use the images.

For reference, the tiger image is available within some package location. See, for example, tiger.pdf from yathesis and tiger.pdf from tkz-base. So these exist within the TeX Directory Structure (TDS), but you'll have to change \graphicspath, or reference them directly (\includegraphics[..]{path/to/image/tiger}).

In short, using a "more desirable" image doesn't make the question better. You should be able to ask the question in such a way that it doesn't require any specific image (that is not contained within/distributed with mwe).

Answer 3

If you want a less boring image you can use the tikzlings package, for example:

\documentclass{article}
\usepackage{tikzlings}
\begin{document}
\tikz{\sloth}
\end{document}

There is no tiger in tikzlings though.

For the tiger can include the original source of the .eps file with filecontents. Here the outline only, to keep the code shorter:
