How to read picture from Excel?

Question

Hi all,

I have an Excel file. The file contains several pictures in cells respectively. Each picture's property in cell is set to "Move and size with cells" to fit itself in individual cell range.

Now I want to write a method to read it to my C# application, how to do this?

I have search a day from Google but I just find too many article about write picture to Excel but lack of read picture. Hope someone can help me here.

Thank you very much.
