"Estou tentando enviar fotos por e-mail usando o" Compartilhar encanto "no Windows 8."
Você precisa verificar a foto em um aplicativo baixado da Windows Store.
Como usar o charme de compartilhamento
This charm works only when used with apps from the Windows Store and it is used to share items using other apps. These items can be web addresses (links), multimedia files (photos, video, music, etc), files from the SkyDrive, etc. Items can be shared via e-mail or with people from your People app.
In Windows 8.1 you can also use this charm to take screenshots and share them using a Windows app.
In Windows 8, trying to use the Share charm on the Desktop or from desktop applications will get you to nowhere, as it will only say that "Nothing can be shared from the desktop".
