I have created a change in the "InsertHyperlinks" function so that when there is an image, the function creates links in the urls and does not modify the source of the image:

Function InsertHyperlinks(ByVal strMessage)

    Dim objRegExp
    Dim objMatches, objMatch
    Dim lngStartPos, lngEndPos
    Dim strURL
    Dim strTempMessage
    Dim strRuteImg1
    Dim strRuteImg2


    'Initilise variables
      strTempMessage = ""
      lngStartPos = 1
      lngEndPos = 1
    strRuteImg1 = "<img src="" http://www." rel="nofollow - http://www."
    strRuteImg2 = "<img src="" https://www." rel="nofollow - https://www."
    
    'Renombramos la ruta de la imagen
    strMessage = Replace(strMessage, strRuteImg1, "[RuteImg1]")
    strMessage = Replace(strMessage, strRuteImg2, "[RuteImg2]")
     
      'Create object
      Set objRegExp = New RegExp

    
    'Match URL's
    objRegExp.Pattern = "((www\.|(http|https|ftp|news|file)+\:\/\/)[&#95;.a-z0-9-]+\.[a-z0-9\/&#95;:@=.+?_,##%&~-]*[^.|\'|\# |!|\(|?|,| |>|<|;|\)])"
    objRegExp.IgnoreCase = True     
    objRegExp.Global = True
    
    'Excure regular expression
    Set objMatches = objRegExp.Execute(strMessage)
     
    'loop through each text link found
    For Each objMatch in objMatches
    
           
            'Get end postion
            lngEndPos = objMatch.FirstIndex
           
            'Place in to temp message string
            strTempMessage = strTempMessage & Mid(strMessage, lngStartPos, lngEndPos - lngStartPos + 1)
    
            'Call Href function to build hyperlink
            strTempMessage = strTempMessage & GetHref(objMatch.Value)
    
            'Get the start position
            lngStartPos = lngEndPos + objMatch.Length + 1
      Next
       
      'Replace the text URL in the string with the hyperlink
      strMessage = strTempMessage & Mid(strMessage, lngStartPos)
    
    'Renombramos la ruta de la imagen al estado original
    strMessage = Replace(strMessage, "[RuteImg1]", strRuteImg1)
    strMessage = Replace(strMessage, "[RuteImg2]", strRuteImg2)


      'Retun function
      InsertHyperlinks = strMessage
End Function


On the page that saves the text I have changed it to:

        'If there are no hyperlinks already look to convert text links to hyperlinks
        If InStr(1, strEmailBody, "<a", 1) = 0 AND (InStr(1, strEmailBody, "<img", 1) = 0 OR (InStr(1, strEmailBody, "<img src="" http://www." rel="nofollow - http://www." , 1) > 0 OR InStr(1, strEmailBody, "<img src="" https://www." rel="nofollow - https://www." , 1) > 0)) Then
            strEmailBody = InsertHyperlinks(strEmailBody)
        End If

I add this code to verify that there are no typos in the image url or changes of place or double spaces, etc. If the src of the image is not the same as in the function it does not do it.

This is for the forum programmers in case they are interested and want to adapt them for a new version. If the moderator likes what I've done and wants to delete this post from the forum, I don't care. Because I write it for the forum programmers.

I hope it is understood because I am Spanish and I translate with the Google translator.

So far it's going well for me and I haven't had any problems or complaints.
