Inserting a picture in an equation

Can I insert an image into an equation?

Is there any method to insert a picture in an equation? I am trying to write an equation where one of the elements of the equation is a small image. I need to obtain a pattern like this:

2 * image1 + 3 * image2 = image3 (equation number)

Please note, one simple way is to make a figure and put all of these elements in it and use \includegraphics to load it into LaTeX document as a figure, however, I need to have an equation with the above structure, not a figure.

You can use \includegraphics in math mode.

so

\begin{equation}
2*\includegraphics{image1} + 3*\includegraphics{image2} = \includegraphics{image3}
\end{equatioon}

I need to be able to adjust the position. How can I make the center of the figure along the text line? – Fluid Oct 25 '12 at 18:09

Any mechanism for moving a box would work, perhaps the adjustbox package is the easiest. – David Carlisle Oct 25 '12 at 18:13

@DavidCarlisle An example would be super helpful. – Translunar Nov 06 '18 at 15:30

@DoctorMohawk better to ask a new question than comment on old answers but basically adjustbox package lets you go \includegraphics[valign=c]{...} to get a vertically centred image. – David Carlisle Nov 06 '18 at 16:47

More precisely \adjincludegraphics[valign=c]{...} – Spherical Triangle Nov 24 '19 at 17:45

@SphericalTriangle I'd recommend loading adjustbox with the export option so the keys are added to the standard \includegraphics command, – David Carlisle Nov 24 '19 at 18:22
