Why can't I drag and drop just anything onto MVOW?

The main things that people want to drag and drop onto MVOW but can't are:

• Images and documents from other web pages; and,
• Images and documents from emails in Outlook (or whatever mail client you're using).

In general, you can't drag and drop anything on to your browser for upload unless it's a file on your computer. Images and documents from other web pages aren't on your computer as such, and images and documents attached to emails aren't actually files on your computer… they're embedded in other files, and even databases.

My suggestion would be that you drag and drop those items into some temporary storage folder on your computer, then drag and drop on to MVOW.
