Embed download link in an image

Hello,

I am trying to add an image with a link to download a document, currently I am using the plugin which displays a button with a link.

How can I change the appearance of this button and make it an image instead?
just copying the link from the button didn't work

Thank you for your help.

Hi Bernard,
You can modify the Content plugin in file: root > plugins > content > edocmanlink > edocmanlink.php
Thanks
