Thank you. Much appreciated. 

Thanks for your reply. Yes, I have it set like that but you see the difference to my Speed Dial 2 screenshot - your thumbnails are convex. I would like to select flat like in my example.

Hi.

Best if I show what I want to achieve. I am moving from Speed Dial 2 and attach a screenshot from that extension. I want to have the same flat icon as seen here not a convex curved icon and just a slight bottom shadow or none at all. I like this because it is a cleaner image to my eye.

I guess that's a 'it can't be done.' then?
