Hi PPTX team,

for the above code it just replaces the whole template with the single image. I would be very happy and appreciate you help if it could replace only an image inside the provided template.

Please let me know or suggest me any at earliest as my project for ppt rendering has come close to deadline and im stuck with image replacement. Many many thanks in advance.

With Regards,
Saranya

In future, please don't cross post. It creates annoying extra work for me, and doesn't make it any more likely you'll get an answer.
