Accessing object in iframe using VBA

It is sometimes tricky with iframes. Based on html you provided I have created this example. Which works locally, but would it work for you as well?

To get to the IFrame the frames collection can be used. Hope you know the name of the IFrame?

Dim iframeDoc As MSHTML.HTMLDocument
Set iframeDoc = doc.frames("iframename").document

Then to go the the image we can use querySelector method e.g. like this:

Dim img As MSHTML.HTMLImg
Set img = iframeDoc.querySelector("div table[id='table1'] tbody tr td a[href^='https://stackoverflow.com'] img")

The selector a[href^='https://stackoverflow.com'] selects anchor which has an href attribute which starts with given text. The ^ denotes the beginning.

Then when we have the image just a simple call to click on its parent which is the desired anchor. HTH

Complete example:

Option Explicit

' Add reference to Microsoft Internet Controls (SHDocVw)
' Add reference to Microsoft HTML Object Library

Sub Demo()

    Dim ie As SHDocVw.InternetExplorer
    Dim doc As MSHTML.HTMLDocument
    Dim url As String
    
    url = "file:///C:/Users/dusek/Documents/My Web Sites/mainpage.html"
    Set ie = New SHDocVw.InternetExplorer
    ie.Visible = True
    ie.navigate url

    While ie.Busy Or ie.readyState <> READYSTATE_COMPLETE
        DoEvents
    Wend
    
    Set doc = ie.document
    
    Dim iframeDoc As MSHTML.HTMLDocument
    Set iframeDoc = doc.frames("iframename").document
    If iframeDoc Is Nothing Then
        MsgBox "IFrame with name 'iframename' was not found."
        ie.Quit
        Exit Sub
    End If
    
    Dim img As MSHTML.HTMLImg
    Set img = iframeDoc.querySelector("div table[id='table1'] tbody tr td a[href^='https://stackoverflow.com'] img")
    If img Is Nothing Then
        MsgBox "Image element within iframe was not found."
        ie.Quit
        Exit Sub
    Else
        img.parentElement.Click
    End If
    
    ie.Quit
End Sub
