Jim, Thank you for guiding me.
Actually want to replace thumnail with along with the book being replaced using request xml as:
.........
<package action="replace" .........../>
<dataPath>.............</dataPath>
<thumbnailData> Base64 encoded binray of image</thumbnailData>
OR
<thumbnailLocation>path of image file</thumbnailLocation>
Book gets repaced successfuly but image is not being replace . I don't know whts going wrong.
Is ther any other way to replace the files on ACS server instead of using Packaging Sevice.
NOTE: I have written .NET to ACS communication protocol and using that to add or modify the books and distributors on ACS.
Thanks.
