Hi, the only thing I can suggest here is to get the buttons url or make a button as an image & where I have written in the script “your image url go's here” put url of the image of the button there.
To try & mix this with the BV’s code is beyond my scope, but maybe another member might know. But the above will work.
HTML Code:
<p align="right"><font face="Verdana,Helvetica" size="3"><a href="mailto:Remove this text and enter your friends email address?subject=Reply from an article about an *****.&body=Hi:%0A%0AHave attached the article about an *****.%0AThis is the email address of the site owner admin@collectors-info.com%0AAnd this is the main site address www.collectors-info.com%0A%0A%0A%0A%0AHope your well!%0A%0A%0A%0A................"><img src="your image url go's here" border="0"></font></p></button></a></font></td>
