Desktop option disappeared

[sandyocean]

Windows 7. Windows Live Mail email.

I have some pictures saved to my Desktop that I often include in emails I send out.

To include the pic I go to Insert and then click on 'single photo' and get a drop dwon box. From there I normally select Desktop'and then the photo I wish to insert.

BUT Desktop has just vanished from that drop down box. There is Downloads, Libraries, Pictures, C drive, etc BUT NO dektop option anymore. What do I do to restore that please???
