Map of attachment insertion

Question

I have a map with String value and list of attachments. I am getting those by inputfile but not being able to insert those. Please find my snippet as below. Can someone please help?

Apex page:

    return null;
}

} The list name listtoinsert size is always zero here.

Jeff Douglas has a blog entry on this. Here are the basics:
