Thanks for suggestions, Orange Blossom and Romeo29. I bothered with this message in the first place because online image instructions did not work. I gather the instructions are in flux, which suggests to me that somebody knows they don't work, and so here's a third suggestion, without change to my earlier two.
3. Remove the non-functional image attachment guidance in the "Do I have a virus, ..." forum and replace it with a working alternative.
Please don't see me as arrogant: I'm an Electronic Eng, 1971, well retired and quite obsolete but well educated and dedicated to quality communications. We plebs need that, and when advisors don't verify their sources, they may not be helping.
Orange Blossom, your reference to "gif, jpeg, and jpeg images" gives me pause, but beyond that annoyance, my experience is that a .jpeg image installed as instructed was quietly rejected by Bleeping and the whole message scrapped without notice - second time around, I noticed that was within the total message but off-screen. There's no record now that my earlier message was ever sent, so I have to repeat that half-hour's work from scratch, watching carefully this time around for any sign of trouble.
Same day, different context: your reference to Autostarts is now obsolete. With my background, I can cope. Some of your users will not.
As well, [img=http://static.giantbomb.com/ etc. leads me down a blind alley.
This is not about mistakes, because they're inevitable. It's about recognising that experts have a special responsibility to make their help accessible.
At the risk of repeating, I suggest my original suggestions stand.
