I'm using vector theme, imagine I'm writing an article and i want to insert a background image, how can i do it?

There isn't a really simple way to set a background. Your CSS output will be filtered, etc.

If your wiki has a limited set of editors, then you can look at $wgRawHtml, otherwise, you will have to do some CSS hacks using MediaWiki:Common.css or the like.

I tried, I can change everything such as background color but when i use background image then it doesn't show anything

What did you change to get the background color?

I used <css> tag (fron an extensions) and changed the blackquote style. everything goes fine, border created, background color changed but when i replace background-color with background-image, neither border and background image shows
