> Is there any specific advice for users taking screenshots? Crop, use the proper format¹, and optimise prior to sending. Depending on how (with which tool) the screenshot was made, there is lots of room for reducing the filesize. For that, use `optipng -o9 <filename>`. It will reduce the PNG colour palette and apply stronger compression settings, but is still lossless. For small and medium images, PNG is of course the best option. But if a larger area needs to be pictued which exceeds the permitted file size, JPG is still good enough. It may introduce artifacts, but compresses much higher and the relevant info is still visible. > Especially inline ones: those get copied when quoted, cf 2021-09. Hm… this is an issue on the user’s side, specifically the used mail client. If you notice this in your own messages, select some text before opening the reply. The mailer will usually only quote the selected content. > Cheers, > Robin > -- Grüße | Greetings | Salut | Qapla’ Please do not share anything from, with or about me on any social network. “So the Americans are worried about having autistic Englishmen hacking into the Pentagon Computer, but they are seriously considering Mitt Romney having control of the Button.” – Jeremy Hardy about the extradition of the UFO hacker, BBC News Quiz.
