This comic is a reference to the NASA Mars Rover "Curiosity" landing on Mars on August 5, 2012 at 10:31pm PDT (August 6, 2012 at 5:31am GMT). NASA live-streamed the landing, but demand for the feed caused server issues. Thus, the time spent trying to download the landing images could be used as an excuse for being late for work.
The image text is a reference to torrents, which are a more resilient way to download files, due to the decentralized BitTorrent protocol, where the more people there are downloading a file, the most available it is. The name is a play on the file naming convention of release groups who name their files containing data on the file; language (SwEsUb = Swedish subtitles), source (DVDRip = Ripped from DVD), encoding (XviD = XviD codec) and group name (aXXo = aXXo, a well known DVD movie releaser).
Additionally, since this seems to be 256px_x_256px and has a "jpg" file extension it can be assumed that this is low quality image, not a video, and in all likelihood this is a reference to some sort of colonoscopy photo or something much much worse.
