I added the css you provided to remove the hover effect on linked images. Of the 4 green “buttons” on my homepage (www.bagoftees.com), the css worked for the first 3, but not the 4th image (the ‘gift’ image).
It must be something with the page it’s linking to, after running some tests. But I can’t figure out how that linked page is any different than the other 3. Also strange that the hover has the double arrow rather than the usual single arrow.
