[Plugin: NextGEN Gallery] Thumbnail fix for gallery previews?

The thumbnail customization for the photo thumbnails is great, but the thumbnails for the gallery preview images (which then lead to the galleries) look awful: the title text is overlapping with the thumbnail, the borders do not fit the thumbnails, and the thumbnail images themselves are blurry. Can we fix this?
