Delete (variable) string from text area submitted data

I would like to remove images from data submitted through a textareas in classic ASP.

Say a user submits the following:

Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat. <img src="c:\my documents\pictures\mypicture.jpg">Duis autem vel eum iriure dolor in hendrerit in vulputate velit esse molestie consequat, vel illum dolore eu feugiat nulla facilisis at vero eros et accumsan et iusto odio dignissim qui blandit praesent luptatum zzril delenit augue duis dolore te feugait nulla facilisi.

In that case I would like to detect the user is submitting a picture which would render a broken link in the webpage Therefore I need to detect and delete the string <img src= ...>. How can I do that?

Use RegExp:

<%Function StripHTML ( s )
Dim re
Set re = New RegExp
re.Pattern = "<img[^>]*>"
re.Global = True
StripHTML = re.Replace(s, "")
End Function%>
