It’s incredibly confusing to post YouTube videos on here as it’s the only thing that actually works properly or logically and no one comes here expecting things that just work! 🙂
Off the top of my head, the forum will correctly and reliably embed:
- Directly pasted plain text URLs from YouTube.
- Directly pasted plain text URLs from Twitter tweets.
- Some other directly pasted plain text URLs from various sites. Try it? The EDIT link is your friend.
- Plain text links copied into the IMG dialogue box to photos anywhere on the web so long as a) they end in an image filename extension like .jpg or .png, and b) the host site doesn’t actively block hotlinking. I like to use right-click / “Open image in new tab” to test this before copying, it’ll tell you whether it’s a sensible URL and will also process and discard any redirection code which might cock up the linking.
It will probably handle BBcode, the stuff in [square brackets] sometimes offered by hosting sites as forum embedding code. This can be hit and miss, some code is blocked or unsupported.
It will probably not handle raw HTML beyond a couple of exceptions because it’s a huge security risk. (I think maybe code from Flickr works? Or that might just be BBcode again, I haven’t tried it in forever.)
It won’t handle plain text URLs from Amazon, it erroneously thinks that anything coming from Amazon is a Kindle book. You’ll need to put these into the LINK dialogue box as slowoldman says. The LINK function will (almost?) always work, but you’ll get a clickable web link rather than embedded media.
Special case: If you’ve enabled the so-called “fancy editor” in your profile options then some of the above may puke out spurious <div> and <span> markup. Back when it was the only option I used to launder any copy & pasted text via Notepad to strip out any non-printing codes and avoid this issue. Today I’ve just turned it off, you don’t need a fancy editor to do clever things in text.
HTH.
