You can use this function to extract the URL of the captcha image (assuming it's the .jpg one?)
Code:
Private Function CaptchaURL(ByRef HTML As String) As String
'<div id="captchaCanvas" >
'<noscript>
Dim lonStart As Long, strStart As String
Dim lonLenStart As Long, lonEnd As Long
strStart = "<div id=""captchaCanvas"" >"
lonLenStart = Len(strStart)
lonStart = InStr(1, HTML, strStart)
If lonStart > 0 Then
strStart = "<noscript>"
lonStart = InStr(lonStart + 1, HTML, strStart)
If lonStart > 0 Then
lonStart = InStr(lonStart + 1, HTML, "<img src=""")
If lonStart > 0 Then
lonStart = lonStart + 10 'Length of: <img src="
lonEnd = InStr(lonStart, HTML, Chr$(34))
If lonEnd > 0 Then
CaptchaURL = Mid$(HTML, lonStart, lonEnd - lonStart)
End If
End If
End If
End If
End Function
Just pass it the HTML code and it will extract it. Then you can use URLDownloadToFile() API function (do a search for it) to download the image. Then load it into a PictureBox using PictureBox.Picture = LoadPicture("C:\Path\to\saved\image.jpg")
It would have been really helpful if you at least posted the complete HTML or the URL to the page that has the captcha image...
