How to save WPF RichTextBox content (text + image) to the database

Hi

I want to save (and after that also to retrieve) the content of an WPFRichTextBox (text + image) to/from the database.

I found this: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/750a654e-b002-4742-8f46-609e93f6ec81 but like the author said, the solution seams not to work for text with image - the image is ignored/removed and only the formatted text is saved and after that retrieved to/from database.

Know someone a solution about this issue?

Best regards,

Vali
