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.
