@xGreylee this feature was landed on jsreport 4.3.0 check the updated docs for it
Each image generated by docxImage generates a bookmark that points to the new image, customizing the bookmark (with bookmarkName option) will allow for other images to be able to create hyperlinks that target this specific image (just make sure to make the hyperlink of an image dynamic too with handlebars, the requirement is that the target resolves to #bookmarkName). using these two features, the custom bookmark name and the dynamic hyperlink target will allow to achieve dynamic linking between images in the document.
