# ...insert a picture?

If pdflatex is the tex engine then you can include JPG, PNG, and PDF without any problems. You'll need to put

\usepackage{graphicx}

in the preamble. Make sure that the pictures are in the same folder as your tex file and use the \includegraphics{MyPicture.pdf} command to include your picture (assuming your picture was named "MyPicture" and was a PDF file). You've got plenty of options that go along with the command. Here are some of the most important ones:

• width=                 (set the width of the image)
• height=                 (set the height of the image)
• keepaspectratio=                  (make sure the image doesn't get stretched)
• scale=                 (set the scale of the image)
• angle=                 (set the angle of rotation of the image)

If you want the picture to also have a caption, put it into the figure environment.

People new to $latex \LaTeX$ get frustrated that their figure is moved to someplace they didn't want. Use [h] or [h!] once you're in the figure environment like this:

\begin{figure}[h]
\includegraphics[width=2in, angle=45]{PythagoreanTreeB5.pdf}
\caption{This is a Pythagorean Tree rotated $45^{\circ}$ counterclockwise.}
\end{figure}

Here's the tex file in the screenshot above illustrating the specifics: AddPicture (tex). The picture is here: PythagoreanTreeB5
