By default, the baseline of an image is at its bottom. So, adjacent images would be aligned at the bottom. However, alignment at the top, or vertically centered alignment, may be desirable instead.
We will use the \height macro for shifting to get vertical centering. Let's take a look at the following steps:
Load the
graphicxpackage. For testing, or if you don't have images, add thedemooption to use black rectangles in place of images:\usepackage[demo]{graphicx}In your document, use the
\raiseboxcommand, together with half of the\heightcommand:\raisebox{-0.5\height}{\includegraphics[height=4cm, width=8cm]{filename1}} \hfill \raisebox{-0.5\height}{\includegraphics[height=2cm, width=4cm]{filename2}}Your images, in the demo case, black-filled rectangles, will be vertically centered aligned:
