How do I import data and insert pictures in the Execl file at the same time?

Because the project needs to export the data to the EXECL document at the same time also need to export the picture in, in the processing is encountered some problems, here to record.

First the code is written, then put the test server to execute the error, reported that the COM class factory in the CLSID {00024500-0000-0000-c000-000000000046} component failed because of the following error: 80070005.

This workaround is basically based on the internet, but it is important to note that after you set up permissions, you also need to assign permissions to the Office folders installed on the server.

Permissions problem set up after debugging code, the online search for data are inserted first, and then at the end of the data inserted in the picture, instead of every line I want to have pictures, so do not meet my needs, so I look at the online code of the whole bar.
