these thumbnails are generated in the bg by rage_thumb and will appear once generated (or already found cached). it'll generate new thumbs if modified dates are equal or newer on tthe src vs the thumbnail cache. the caches store 160xN thumbs (keep aspect) with 70% lossy jpeg quality in an eet file with one thumb per 10 second interval. so it has limited accuracy.v-0.4.0
