Can you tell me which thumbnail is an image and which one is a video without clicking on it? Not really.. both the thumbnails look the same. My suggestion is to make it more easy to distingush between a video and image. Possibly the video thumbnails could be watermarked with a transparent play watermark here the thumbnail was watermarked with a transparent play . So you can easily know its a video. Even in the /media would be useful. I find the icon blends in too much and is too small.
