placeholder image thumbnails are smaller than real image thumbnails
When I search the demo site for (empty string) (a.k.a. '*') in All Categories, I see the pages and blog posts (i.e. not just ads) appear in the search results. That may just be due to having certain admin settings in place.
However, the thumbnail that get displayed for the blog post shown is smaller than that displayed for the ad below it. I just want to point that out in case it was an oversight. I want all search results to have a common size thumbnail, regardless of whether it's a placeholder image or not.
