Abstract: The paper showcases a re-designed version 2 of the ALMA WebQL web service - available through the JVO ALMA FITS archive - which allows users to preview ALMA FITS files of any size without having to download large amounts of data to user PCs. Large FITS files (i.e. > 20GB) can be previewed smoothly in a web browser running on a relatively low-spec client PC. Users can interactively zoom-in to selected areas of interest with the corresponding frequency spectrum updated in near realtime (network connection-dependent). At a glance users gain access to large images as well as the corresponding frequency spectra that are visible both at the same time.
