To change the position of an image in LaTeX, use the \raisebox command. For example, to lower an image by 0.5 inches, use:
\raisebox{-0.5in}{\includegraphics{example.pdf}}
If you want to move the image to the left or right, use \hspace. For example, to move an image 0.5 inches to the right, use:
\hspace*{0.5in}\includegraphics{example.pdf}
Finally, you can also use the \raisebox command to move an image up or down. For example, to move an image up by 0.5 inches, use:
\raisebox{0.5in}{\includegraphics{example.pdf}}
