Replace placeholder with image in docx

Our requirement is like we have to insert the image file with hyperlink in the docx file in the specific “place holder”. This placeholder can be in any document page#.

Could you please provide the sample code (with explanation) for getting placeholder and replacing it with image.

Note:
On click of image it will redirect the user to the specific url location in the new browser.

Hi Laurie,

Thanks for your inquiry. Could you please attach your input and expected output Word documents here for testing? We will investigate the issue on our side and provide you more information.


We have to insert image in the docx placeholder on fly (with image and hyperlink) which is inserted from GUI.
If image/url is not inserted from GUI then we have to remove the placeholder else replace placeholder with image and hyperlink.
Please find the attachment for expected input and output docx file.

Hi Laurie,

Thanks for sharing the document. Please use following code example to achieve your requirements. Hope this helps you. Please let us know if you have any more queries.
