Adding image button to a complex literal control - VB.NET

I have the following line of code which works perfectly. It was written for me so it's tricky to understand exactly what is happening. It displays an image with a price overlayed on it. When you click the image, it brings up an enlargement using Nyromodal. I wish to now add a Buy Now button to the enlargement image but can't work out the syntax. Ideally I would like to add something like this..

<asp:ImageButton ID="imgPaypalIcon" runat="server" ImageUrl="" OnClick="imgBtnPaypal_Click" />

Here's that nasty line of code...

Dim liByLiteral As New LiteralControl("<a href='https://example.com/catalog/images/" & filenameAndPrice(0) & "' class=""nyroModal imageThumbnail"" style=""padding:3px;"" rel=""gal" & DataBinder.Eval(e.Item.DataItem, "accountID").ToString & """ title=""" & filenameAndPrice(2) & " - PRICE: £" & filenameAndPrice(4) & """ onclick=""openImage('" & filenameAndPrice(1) & "', '" & txtItem.ClientID & "', '" & filenameAndPrice(0) & "');""><img class='lazy" & opacity & "' data-src='https://example.com/catalog/images/thumbnails/" & filenameAndPrice(0) & "' src='./files/images/loader.png' /><p><span>£" & filenameAndPrice(4) & "</span></p></a>")

What I have tried:

I have tried adding the image button in various places but keep getting an error.. Usually error states it is expecting a ')'

You can't! MSD documentation states that:

LiteralControl

Represents HTML elements, text, and any other strings in an ASP.NET page that do not require processing on the server.
VB

VB
Public Class LiteralControl
Inherits Control
Implements ITextControl

ITextControl interface "Defines the interface a control implements to get or set its text content."
