I have a problem with importing pictures in Excel. I usually use ClosedXML, but it cannot import pictures and first have to be saved in ClosedXML, and open in OpenXML, to insert a picture. As a result, when you open a file, I get an error.
"We found a problem with some content in 'error.xlsx'. Do you want us to try recover much as we can? If you trust the source of this workbook, click Yes."
If I save a picture in the Excel file already manually create everything works fine. The problem occurs when you save after ClosedXML.
