RegEx need help to grab the src from the IMG tag.

[simpleonline]

Hey guys I'm trying to setup my RegEx to grab the link of <IMG> SRC tags.

Right now my code doesn't do anything when I have it setup this way.

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim net As New Net.WebClient()
        Dim src As String
        src = net.DownloadString("http://www.wikihow.com/Make-Easy-Homemade-Biscuits")

        ' Create a match using regular exp<B></B>ressions
        Dim m As Match = Regex.Match(src, "")

        ' Spit out the value plucked from the code
        RichTextBox1.Text = m.Value


    End Sub
End Class

Any ideas on how I can setup my regex to grab the link of the src?

Example:

src="hxxp://myimageishere"

Thanks
