How to replace placeholders with multiple images

[MayuriBParticipant]

Hi,

I have a requirement of generating a report out of pre-defined document template from my MVC application. While generating report I have to replace placeholders in the template with text or images. I am using OpenXmlPowerTool’s Regex feature to replace placeholder with simple text or paragraph contents.
But I am unable to replace the placeholder with multiple images using Regex feature. Could you please suggest or share the code or method to achieve this?

My another issue is I am not able to replace placeholders in headers in the document. I searched for the HeaderParts and a method to replace placeholder from this headerpart but did not find any way. Please suggest how to do this.

Thanks.
