@nestort It appears that AndStatus still cannot show a preview of remote media files that it didn't download. Currently only locally downloaded images/video files are shown at attachments and may be viewed. As a result, media files that are larger than configured in "Attachments -> Maximum size of an attachment" are not shown at all.
We need to store locally a preview image (if it is available) and show that image. Or at least show a text link to the media file, for which even preview image couldn't be downloaded.
I created the ticket for the feature https://github.com/andstatus/andstatus/issues/502
