I always using external image to paste the picture in the mediawiki. If I use internal phrase of mediawiki, the direct links with the png ot jpg external file name will auto show the picture in the mediawiki. But I want to

1. resize the picture and add the frame line around the picture so I want just using html phrase and don't want using wiki's phrase. I find the rawhtml function and it seems can provide full html support, but even if I add the command - "$wgRawHtml = true" in the localsetting file ,it(rawhtml) seems not work (still show the picture automatically). If I want to enable some phrase with html code and remove all the mediawiki support temporarily, how could I do?
and
2. just want the picture link using the type of hyperlink like the result of vbb code [url=XXXXXX.png]hyperlink name[/url] Because the picture will auto showing after I paste the direct link with png external file name , I can't use this method to show the hyperlink like below example - [http://XXXXXXXX.png hyperlike name]
3.Then,if I use the nowiki tag, it seems not only stop support mediawiki phrase, but also I can't use the html phrase, is this true?
thanks anyone answer my questions
