RedNotebook and pictures

I wanted to document my dryer’s clogged with lint, cleaning. So I thought I’d use the insert picture option, to show before and after pics. But no picture showed…only a text path. How useful…NOT! I thought this can’t be right and Googled FAQs and RedNotebook questions. Because obviously why would you expect to see a picture when you choose insert picture? You know like you would with MS-Word or LibreOffice Writer.
