A related question: is it possible to use something like the HTML tag "img", to display within a post an image located elsewhere, rather than uploading the image file to LL? I have tried inserting HTML code like
<img src="http://upload.wikimedia.org/wikipedia/en/e/e1/Elvis-Costello-This-Years-Model.jpg">
but it fails for me.
You can't use the HTML img tag, but there's a BBCode tag for IMG that works in a similar manner and allows you to show it inline, like this:
[img]http://upload.wikimedia.org/wikipedia/en/e/e1/Elvis-Costello-This-Years-Model.jpg[/img]
You can get that by pressing the "insert image" button in the toolbar (second row down, first icon on the left) and then pasting in the URL between the img tags.
P. S. Thanks Mark: It seems to be access limitations of the site I am linking to: that BBCode method from "Insert Image" failed with the Wikipedia image, just giving a missing image question mark:
(http://upload.wikimedia.org/wikipedia/en/e/e1/Elvis-Costello-This-Years-Model.jpg")
but this one works:
There's an extra quote in what you pasted for that image in your test :)
[img]http://upload.wikimedia.org/wikipedia/en/e/e1/Elvis-Costello-This-Years-Model.jpg"[/img]
It works if you remove the extraneous quote.
