To insert images into a LaTeX document, users can utilize the \includegraphics command from the graphicx package. While some users are accustomed to converting images to PostScript format, it is possible to include non-PostScript formats like PNG and JPEG directly in certain setups, particularly with pdflatex. Users employing MikTeX can include PNG files without conversion, and EPS files generated from tools like gnuplot or Maple are also compatible. However, non-bitmapped images may require conversion to EPS for proper handling. Some IDEs, like WinEdt, provide a pdflatex button that simplifies the process of compiling documents with non-PostScript images. Overall, understanding the specific capabilities of one's LaTeX setup is crucial for successfully including images.
