I am trying to fill a docx template dynamically using the golang package "github.com/lukasjarosch/go-docx".

I can replace all the text fields accordingly with this code:

package main

import (
    docx "github.com/lukasjarosch/go-docx"
)

func main() {
    // some logic here

    replaceMap := docx.PlaceholderMap{
        "personName":            name,
        "companyName":           company_name,
        "cityName":              city_name,
        // .....
    }

    // read and parse the template docx
    doc, err := docx.Open("rental_contract_template.docx")
    if err != nil {
        panic(err)
    }

    // replace the keys with values from replaceMap
    err = doc.ReplaceAll(replaceMap)
    if err != nil {
        panic(err)
    }

    // write out a new file
    err = doc.WriteToFile("replaced.docx")
    if err != nil {
        panic(err)
    }
}

Now I want to insert an image at {QRODE}. I found out that unfortunately, this package does not provide this functionality. I am lacking the knowledge to work with XML directly. I am supposed to not use "github.com/unidoc/unioffice".

How can I insert an image at that specific place?
