Dear Suriya,
the sample is not as expected.
we want to perform mail merge for multiple images (the number of it may be different every time).
we should be able to mailmerge All of these image , without specifying for each image a different merge field in template.doc.
on your example there is a specific mergeField name for each image you want to replace with. can you please provided an updated example (.net 6 core, is preferable).
