Honestly Rated 3 out of 5 stars
Did you photoshop this preview images? I'm trying to get a similar result and have defined fixed dimensions for the thumbails and created icons with the exact size of the thumbnails, but no matter what I do, they are always blurry. Therefor I won't use Fast Dial. Apart from that it's a fine little addon.This review is for a previous version of the add-on (4.0).
No, they are not photoshopped. Are you sure you have the right ratio of the logos? (400x300) If you are having trouble creating them by yourself, take a look at the many premade logos at our site: http://userlogos.org/logos, or use one of our tutorials for making logos.
