[Tex/LaTex] How to put text in an existing figure/image (maybe with tikz?)

How to superimpose LaTeX on a picture?

I was wondering if it's possible to have an existing image (possibly in a figure environment) and then add text at arbitrary locations within that image/figure. Does maybe Tikz allow something like that?

For clarity: This wiki link has this synapse image with hyperlinks at the beginning of arrows that point to specific parts of the synapse.
When clicking on the image I only see the png file and the hyperlinks disappeared and only arrows without description pointing to stuff so I would like to reintroduce these texts.

Best Answer

No doubt you can use TikZ but if you just want to overlay text you don't need any extra packages at all


will write "hello" over your image.
